maria's questions

My laptop says the disk is full, so I'm trying to make some space by removing some files. But the ls output doesn't make sense for me. The Downloads directory, in reality, is empty... I guess the issue is elsewhere, but I have no idea of how to start solving the problem.

The problem persists after the new system installation.

ls -lSh output:

I'm using Ubuntu 16.04 on Dell Vostro.

I have a problem to use external hard drive. When I plug it, first it works, but in some time it unmount by itself (while reading data or not).

While the drive was mounted, I tried to open GParted, got the warning input/output error during read on /dev/sdb, and had to kill the process in the terminal.

I tried to use smartctl, but it failed:

$ sudo smartctl -a dev/sdb | less
dev/sdb: Unable to detect device type 
Please specify device type with the -d option.

First I thought that the external drive is broken, but I've tried with another one, I was also trying to change the USB cable and the behavior is exactly the same.

I still can see the drive in Nautilus, but I can't open the folder (Unable to access location. Can't mount file) and I can't see it with lsblk command.

I use the USB ports with my phone without any issues, so I assume that they're fine.

I've run dmesg in terminal. The output is long, I'm pasting only the lines which point to errors:

[   22.055520] usb 2-1.5: device descriptor read/64, error -110

I didn't find what error -110 means.

UPDATE 2:

Thanks to the comment I've managed to run smartctl. There is part of the output of smartctl -a /dev/sdb | less:

After installing the actualization more or less one week ago, I started having problems with Firefox, which seems to me connected rather with some error in installation of the updates than with the actualization itself.

Some websites doesn't display the text. The graphics are there, sometimes the title also. Other websites (this one for instance) display correctly.

The easiest to do would be to reinstall Firefox, but unfortunately I don't remember the last password to my Gmail account. I was using the Firefox sync and unfortunately with the crush, it's not my current but previous password which is saved.

I can open my account only using my usual device, and if I try to open Gmail using password saved in Firefox sync, it says "wrong password". I've checked in Firefox's preferences - the Gmail password saved there is the previous one.

How can I check what is wrong Firefox installation and repair the errors?

I'm using LibreOffice with Ubuntu 16:04. The system is in English. I wanted to change UI only for LibreOffice to Polish.

In LibreOffice in tools -> options there is only English (and English US) as possible language for UI.

I've checked via terminal, libreoffice-l10n-pl and libreoffice-help-pl are installed. In System Tools - > Language Settings Polish is installed.

Here is an output of locale command:

I've recently installed new distribution (ubuntu 16.04, before it was ubuntu 14.04). Before installation I've copied my data on external hdd. When I was trying to copy it back, I was not able to access it. It seems that the file system (ext4) is damaged. I was able to see it with fdisk -l commnad but not to mount it. I've created mounting point in /media named external

I've run sudo mount /dev/sdb1 /media/external

The output is:

 mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
        missing codepage or helper program, or other error

      In some cases useful info is found in syslog - try
      dmesg | tail or so.

I've tried mount -t ext4 /dev/sdb1 /media/external

Output:

mount: special device /dev/sdb1 does not exist
maria@maria-Vostro-3360:/media$ 

I was also trying to boot the computer on live ubuntu 14.04, the system which was installed when I was copying the data on the external disc, but it didn't help.

Gparted shows unknown file system and under the details there is following:

I've run testdisk. I'm not sure if I've done it correctly (for exemple I don't know if I should choose no partitionned or there was one partition on my disc. I've choose the default options, i.e. partitioned, type - Linux. The result of deep search was"

Disk /dev/sdb - 320 GB / 298 GiB - CHS 38913 255 63
     Partition               Start        End    Size in sectors

Since it seems the filesystem is damaged I wanted to run fsck. I've run sudo fsck -r /dev/sdb1 and I got this:

fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
Superblock has an invalid journal (inode 8).
Clear<y>? 

Since I don't understand really what I am doing, I typed no, I don't want to mess it up more and loose my data defenitly. The output was:

fsck.ext2: Illegal inode number while checking ext3 journal for /dev/sdb1

/dev/sdb1: ***** FILE SYSTEM WAS MODIFIED *****

/dev/sdb1: ********** WARNING: Filesystem still has errors **********

/dev/sdb1: status 12, rss 3040, real 816.797699, user 0.004000, sys 0.000000

UPDATE: In testdisk I've tried to check the non partitioned media. Than Advanced - filesystem utiles shows primary partition with unknown filesystem. I've tried to change it to ext4 and than entered list. The output was: Can't open filesystem. Filesystem seems damaged.

UPDATE 2: Following @heynnema's advice I've managed to recover something but I still don't know exactly what. All the files and directories are in one directory lost+found with wired names (starting by # and after different numbers). Some of files has name of a file that I had in my computer but the name doesn't match with the content. To open the folder lost+found I have to use sudo and I'm not able to copy it:

root@maria-Vostro-3360:/media/maria/9db3c007-4387-4ea8-a61c-b12fa10049bc/lost+found/#3670019# cp -i /media/maria/9db3c007-4387-4ea8-a61c-b12fa10049bc/lost+found/#4718697/ /home/maria/Desktop/odzysk/1
cp: omitting directory '/media/maria/9db3c007-4387-4ea8-a61c-b12fa10049bc/lost+found/#4718697/'

The .odt file after opening it looks like this: It was loading very long and finally I got the message that it contains some invalid characters. While I was trying to change the encoding, the file closed due to some error.

I've just installed ubuntu 16.04 and installed ubuntu mate. I've added other keyboard layouts via language indicator on the right upper panel. The indicator shows different layouts, I can switch between them using the applet or the shortcut super+space, just the layout doesn't change - it's the layout I've choosen during the installation. When I log in on unity, I'm able to switch between different keyboard layouts (although I had to add them to unity desktop separately).

In mate desktop I've added also new layouts to keyboard preferences (in system preferences. Still nothing happens when I'm switching between different layouts.

UPDATE

I've run gsettings get org.mate.peripherals-keyboard-xkb.kbd layouts

The terminal output is: ['pl', 'ara', 'fr']

UPDATE

I'm trying to create a symlink in my home directory to a directories and files on my data partition. I've tried:

~/Documents$ ln -sv ~/Documents/saga /media/mariajulia/485f3e29-355c-4be3-b80a-1f5abd5604b6/mariajulia/Downloads/saga..doc

to create a symlink named saga in my Documents directory in my home folder. The terminal output is:

ln: failed to create symbolic link ‘/media/mariajulia/485f3e29-355c-4be3-b80a-1f5abd5604b6/mariajulia/Downloads/saga..doc’: File exists

I was checking the content of ~/Documents with ls -a , there is nothing but . and ... In general my home folder is empty, it's just a fresh system installation.

I have some problems with my computer. I can't boot, so I've booted it using live USB. I wanted to check what's going on with my computer, but I don't know how to mount the partition.

On my disc (internal), I have two physical partitions, sda1 (/) and sda2, which is divided into two logical partitions - sda5 (swap) and sda6 (/home).

sda1 and sda6 are not mounted. I was trying to type mount /dev/sda6 in the terminal, but the output is:

mount: can't find dev/sda6 in /etc/fstab or /etc/mtab

Indeed, the content of /etc/fstab is:

overlayfs / overlayfs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda5 swap swap defaults 0 0

The content of /etc/mtab/ is:

/cow / overlayfs rw 0 0

If there is a need of any other details. I'll complete the question.

While doing the first installation of Ubuntu 12.04 I've made a separate partition for the system, to be able to reinstall it without having to clear all data. So I have / on one partition, and second is divided in 2 logical partitions, one for swap, the other for /home.

    Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors

I'd like to reinstall the system (I've messed up something with the repositories and there are some other problems, I'm not even sure if it's software or hardware...) My point is that if I reinstall the system on / partition, the new /home would be also on /... Now, when I'm installing something, it goes automatically to / and if I download or write something it's automatically placed in /home. Is it possible to indicate to the newly installed system, that the /home is on the other partition without reinstallation of /home (and having to copy the data twice).

UPDATE

I've tried the first solution from the Marty's Fried reply: I've installed / on previous / ("format" box checked) and /home on previous /home ("format" box unchecked). First I've give an other username than previously. Everything seemed to work fine, only I hadn't my home in my home (there was a new user home).

I've repeated the installation, and now all my files are easily accesible, but the system is not working well. I wanted to start by installing classic gnome (I can't find anything otherwise) and I'm not able to open the terminal. There is just the frame of the terminal window, flashing and moving towards the screen. Is it possible that in my home partition there are some problems which may provoke this?

About 2 months ago I've installed ubuntu 12.04 on a new computer. I remember, there were some problems with disc sectors, unfortunately I can't remember now on what it consisted.

I have 15 GB for \ and the rest for \home (total disc space - 320GB). I was pretty sure it's enough. But today after I've installed updates (kernel updates included), I couldn't restart the computer. There was an information, that the \ partition is full, so the computer will be working in low graphic mode, but the next window was not active, so I couldn't enter "low graphics mode". Now I'm working on trial version of ubuntu, using install usb drive.

I don't know how to change the size of the partitions now, but beside that I'm not sure if this would be the solution since I'm not sure if the partition is really full - during the installation, I've made this partition much bigger that it was said in the tutorial and I don't have any special applications (ubuntu, latex, some other small stuff).

In "proprieties" of the system partition is said that total capacity is 15,1 GB and 15,1 GB is used. The output of df -h is:

Thanks for any suggestions

UPDATE

I've followed Saurav's Kumar and oldfred's suggestions.

After this I've recovered about 800 MB of free space. Still I don't understand why my system takes so much space. I'm hesitating a bit with "scary" suggestion of mikewather, but maybe I'll have to take a risk :) Or is there anything else I could do, less "scary "?

UPDATE:

I'm reopening the question since the problem persist. Last time, when I managed to boot my computer, I've made / bigger, but now I have once again full system partition, I don't know why. I wanted to reinstall the system (there are some problems that I don't know how to "divide" in separate questions and I need my computer working quickly). I've downloaded the .iso file for Ubuntu 14.04 - and the system partition got full again. I thought since it's not installation but download, it should be on /home and not /, so why there is no more space after downloading it? And why 25 GB is not enough for /? I didn't install any important things since that time.

In any case I'd like to re-install the system, but I'd like to know why it's happening to avoid the same mistake during the new installation.

According to the replies to that question, my root partition is huge and I didn't install anything important since one year (since the time I changed it's size from 15 to 25 GB).

Thanks

I've just installed ubuntu 12.04. I didn't put my data yet, I want before to make sure that the installation is fine. And I get Disk Utility warning about misaligned partition.

I have / on sda1 and sda2 is extended partition with sda5 for swap and sda6 for /home. There is no other partition on the disc. From other questions about the same problem I've understood that I should boot my computer from live USB and fix the problem with gParted. The problem is that when I boot my computer from live USB stick and enter try mode, both primary partitions are mounted, so I can't do any operation on it.

Since I don't have any data yet, I can even re-install the system, but I should know how do set the installer to align the partitions in right way. I've chosen not to use the install option without partitioning, since I'd like to have /home on separate partition. I could also try to fix it with the present installation, but I don't know how to unmount swap partition (and I'm not sure if it's reasonable).

Here is the output of fdisk -lu:

I have recently installed new system on my disc, Ubuntu 12.04. Installation proceeded without problems, I started installing additional software and put data from other discs. I had already two times bug report, it was quite long, and I have no idea how to acces to log file (which probably is somewhere saved) and since I had to switch off the computer using the button, anything else was possible, here is just a small part of it (what I've noted on paper)

could not write bytes: Broken pipe

speach dicpatcher disabled: edit etc/default/speach-dispatcher

saned disabled: edit ....

and than:

BUG: unable to handle kernel NULL pointer dereference at 0000009c

I've run Memory test in GRUB, everything is fine.

First time it occured when I was using rsync, second time when I was trying to install texlive.

Should I install whole system once again? Or can it be hardware problem? Or something else?

If there is any hardware details which may be relevant, please ask, since I have no idea what is happening, I don't know what kind of information could be useful.

Thanks

P.S.

dmesg output:

I'm using Ubuntu 10.04. I'm affraid I've installed a virus on my computer (I've clicked a link which was a virus), I'd prefere to check if everything is fine.

I've installed clamAV using Synaptic. The installed version was 0.96.5, while the most recent version is 0.97.6. When I was trying to update virus database, I got a warning that the version of clamAV I'm using is outdated. Since I didn't know how to update the software by Synaptic or apt (both show the installed version as the newest) I've uninstalled all and downloaded the recent version from sourceforge. I've unpacked the tar.gz archive, entered the folder but when I type

./configure

I'm getting the message:

configure: error: Please install zlib and zlib-devel packages

When I type

sudo aptitude install zlib zlib-devel

The terminal output says there is no such packages (there is no package zlib-devel and there is many packages which name contain zlib).

I suppose the link contained probably the Windows virus, but I'd prefere to make sure there is nothing in my computer. As well as I'm not sure if the virus, even without harming my system, can send itself to my e-mail contacts or not.

I have two laptops with Ubuntu 10.04 installed. One of them had a problem; I was not sure if it was a hardware or software problem. Sometimes it would suddenly start working extremely slow (it needed a few minutes to open an application, such as a terminal window) and afterward the screen would become grey and inactive. After some time (5-10 minutes) it would start to work normally again.

I've installed Ubuntu 11.04 on an external drive. In the beginning it was working fine, but after some time (quite short) the same problem began to appear when the computer was running the system installed on the external drive. So I thought it was a hardware problem.

Yesterday I had to switch off the computer using the power button, since the problem persisted for at least half an hour. Since that time the system on the external drive has been completely broken; when I'm trying to boot the other computer with the system on the external drive, even GRUB doesn't show up (even after waiting about 20 minutes). When I boot the computer with the internal system, it can see the external drive partitions.

I was thinking that maybe that problem was connected with a virus; I've scanned the computer where the problem appeared with clamav, and found nothing.

Thanks for any tips.

P.S. The computer in question is Acer AS 3810T. CPU: Intel Core (tm)2 Solo processor SU3500(1.4GHz). RAM: 3GB DDR. Video card: Intel Graphics Media Accelerator X4500M HD

The external drive is ADATA HDD NH92.

Here are the screenshots showing the use of processor (on the panel) and System Monitor window (I'm not sure, but I think that there is something strange here, on the first screenshot the indicator of the use of processor is all blue and System Monitor doesn't show bigger use of processor):

The slowing down doesn't happend when I'm doing something which demands more of processor of memory use. Just from time to time.

Processor speed is set on "ondemand" and it's varying from 800 MHz to 1.4 Ghz.

UPDATE:

It seems that it is the memory which is exessively used in the broken computer. The other one (Acer Aspire 2920Z; CPU Intel Premium Dual CPU t2370, 1.73GHz; RAM 2.0 GB), while exactly the same applications (at least the software that I run, I don't know about background processes) are in use, uses much less memory - the first one 95%, the other 60%. Applications used at the moment: two web browsers (Firefox and Chrome) and music player.

2nd UPDATE:

I have now on the top panel sytem monitor's indicators of use of CPU, RAM, system load (?) and swap. In the moment the system freezes first 3 of them are full (show 100%). Swap stays with the margin use, just few %. When it freezes I'm not able to check which process is taking most of CPU and memory, since no window works and either the muse coursor is blocked, or it mooves around the screed but doesn't make any effect. In the moment it freezed I had only the web browser open, but I was not using my computer at all, I just saw the screen loosing colours.

3rd UPDATE

Since I've removed antivirus (clamav), the system is no longer freezing, but still it happens (without any visible reason) to slow down. I don't know if the antivirus was the reason (one of the reasons), since I've removed it I was not using my computer a lot.

I've done memory test by memtest, no errors.

Quite often in the top of the list of processes using the most CPU is flushplugin-installer. Should't I use Firefox? I thought it's not an application demending a very fast processor...

Thanks

I'm trying to make a backup of my /home to transfer all data from one computer to another. I wanted to save the backup on the same computer and than transfere it to another one. For safety reasons, I'm trying to learn how does it work on the computer without a lot of data (the new one) to be sure I won't delete something instead of copying it.

I've run in terminal:

sudo rsync -avz /home/maria /home/guest/backup

and I had as the result:

sent 58797801 bytes  received 23050 bytes  4705668.08 bytes/sec
total size is 100202958  speedup is 1.70
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1060) [sender=3.0.7]

I've tried once again, with the same result. I have no idea, which files were not transferred, what makes the whole backup useless for me (I wanted to do it automatically in order not to forget about something and loose it).

On both computers I have the same system (Ubuntu 10.04). Rsync version: 3.0.7-1ubuntu1.

Thanks for any tips

I am continuing an abandoned thread Arabic reading error, since it was not solved.

I'm using Ubuntu 10.04, Firefox 3.6.14. I've checked for Flash Player, I have the recent version installed.

In the Flash Player window arabic script appears in wrong direction. The letters are displayed from left to right and not, as it should be, from right to left. For exemple http://www.fpnp.net/. The problematic place is the black bar in Flash window with a text below the image on the right. Here the letters are displayed in wrong direction and, by consequence, are not joined. You can see (I hope) the difference between that black bar and the rest of the text.

Hope it will understandable for not Arabic-speaking people.

Thanks

I'm aware of the existence of similar threads on this forum. But any of replies mach to my problem.

I'm using Ubuntu 10.4 and I hadn't problems with fonts till I've decided to use XeLaTeX instead of LaTeX (cf https://tex.stackexchange.com/questions/12347/typesetting-a-document-using-arabic-script/12358#12358). The problem is that I'm not able to compile any .tex document using XeLaTeX, as well as properly display XeLaTeX documentation. As I've learn thanks to mentioned thread, XeLaTeX uses the fonts availables in general in the system.

I was trying yo read fontspec documentation, but it opens in pdf with a lot of white gaps and terminal output (quite long) consist mostly of errors. This are just few lines of it:

Error: Missing language pack for 'Adobe-Japan1' mapping 
Error: Unknown font tag 'F5.1' 
Error (24124): No font in show 
Error: Unknown font tag 'F5.1'

I was trying to compile simple XeLaTeX file:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Linux Libertine O}
\begin{document}

Hello World!
\end{document}

without succes. This is terminal output of compilation:

So font in question is not just uninstalled, but not available, if I'm not wrong. Does it mean that I lack some repositoires?

I was trying also to apply solution from the thread How do I reinstall default fonts?, but the result is:

maria@maria-laptop:~$ sudo apt-get install msttcorefonts
[sudo] password for maria: 
Reading package lists... Done

ttf-mscorefonts-installer is already the newest version.

maria@maria-laptop:~$ 

It seems that is not a usual problem for use of XeLaTeX; nobody in the mentioned thread suggested instalation of anything else than TeX Live.

Thanks in advance

I'm quite new to Linux, but before using it I was hearing that Windows programs, after uninstallation, leaves a lot of remains on the hard disc, and Linux removes all.

I'm using Ubuntu 10.04. To uninstall packages I'm using sudo apt-get autoremove application_name or sudo aptitude purge application_name. Recently I have installed texlive-full and for some reasons I had quickly to uninstall it. After I've entered to terminal updatedb, then locate *texlive* and the output was very long:

maria@marysia-ubuntu:~$

I've used sudo apt-get autoclean without any change. I've installed deborphan and it showed nothing (maybe I've used it in wrong way: just entered command deborphan). Am I doing something wrong or I was told something which is not true?

I would like to know two things: how to remove packages (if I'm doing it in wrong way) and how to clean hard disc from remains of all packages I've uninstalled till now (even if I don't remember what it was exactly). I have Ubuntu Tweak installed but I don't know how to use it and I think I prefere terminal commnands.

Thanks

I'm using Ubuntu 10.04. I would like to create a new account, for other people using my computer. I would like my guest to have access to Internet, text editor and other application installed on my computer without having access to my data (and obviously system settings).

I have added a user "guest" using graphic interface (System -> Administration -> Users and groups). My guest has now access to the application, but not full - wine and VirtualBox are empty (wine has only wine notepad, on VirtualBox there is no virtual machine installed). Internet and chat are fine, but "guest" has the access to anything in the computer via terminal, and I would like to keep him in his guests home (there are a lot of people using my computer, not all of them I know well).

I have found on http://www.ubuntu.pl/ how to change user's privileges via terminal and I'm wondering if the command chmod -vR --preserve-root 700 /home/maria is fine?

/home has two directories: guest and maria.

And how to ensure for my guest the access to applications installed on wine and VirtualBox without installing it once again?

This is an output for guests groups:

guest@marysia-ubuntu:~$ groups
guest adm dialout fax cdrom floppy tape dip video plugdev fuse nopasswdlogin
guest@marysia-ubuntu:~$

And this for marias groups:

maria@marysia-ubuntu:~$ groups
maria adm dialout cdrom plugdev lpadmin admin sambashare guest
maria@marysia-ubuntu:~$

I've freshly installed Ubuntu 10.04 on a new computer. I'm trying to install an application that I need onto it (my old computer is broken and I have to send it for service). I've managed to install texlive, but then I can't install anything else. All of the software I want installed is the same software that I had successfully installed on my old computer previously (using the same version of Ubuntu). I don't understand why the terminal gives this warning (sorry, the terminal speaks half English, half Polish, but I hope it's enough):

I was trying to install other editors as well, with the same result. As I decided that I might be sure that I know the package I want to install is secure, I finally entered "Yes". The installation ended successfully, but the editor doesn't understand .tex files (and the .tex files themselves are known to be good):

?

What's more, I've realised that in Synaptic Manager there aren't any packages which are marked as supported by Canonical....

Any tips? Thanks in advance.

After using update, it's almost fine. I've managed to install 3 applications (texlive, texworks and ekg), and Synaptic shows icons for "supported by Cannonical". But problems with connection persist.

I'm connected to Internet, I can use chat, but sometimes I can't open any web pages. I'm not sure if it this is part of the same problem, or if one is resolved and for the other one I should write a separate post.
