Katai's questions

I was in the process of upgrading an old 16.04 LTS, and seemingly locked myself out with no way back in. Help.

I followed the basic steps:

sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade
sudo do-release-upgrade

During the release-upgrade, everything went smoothly. No error messages, nothing - it's the restart that killed my access to the system. The secondary SSH process started by it on port 1022 times out completely as well.

Now, the problem is, I cannot attempt to connect as root@ip, since that was disconnected. Only connecting with an SSH key is possible.

This is the debug from SSH:

:~$ ssh -vvvvvvvvv atlas

(I edited out name & ip)

What is going on? Why can't I connect? Did I completely brick everything, or is there a chance to somehow recover from this? It's a virtual server, I do not have access to it physically and remote restarts seem to fail now as well.

Help :)

Edit: Since it seems that I won't be able to salvage this, I'll be a bit more specific: What exactly did I do wrong here? What could I have done to prevent this? The SSH debug doesn't give me any feedback on what actually caused the problem and the "reserve" port (1022) that was opened for this specific case, just doesn't work at all.

If I have to lose the whole server, at least I would like to learn from this - but it just seems to "not work", and that's it?

Edit 2: Surprisingly, I managed to access the server again in a "repair" mode offered by the host. What should I do to guarantee access and fix this, now that I'm in? (I have access to all files via VI, they are placed in a /repair/ folder)

I'm usually working with 3x3 Desktops, with the tendency to separate them by active projects or clients for the workday (for example, all consoles going to project A on one desktop, all consoles going to project B on another).

This is fine in most cases, but when there's a lot of stuff going on at once it can quickly become confusing.

Is there some way to label a Desktop? Either on the 3x3 Grid view (when switching around with CTRL+ALT+Arrows), some kind of gnome plugin to just add a Box with a word in it, or a custom background for each desktop?

Maybe there's an obvious solution, but I never really played around with gnome. I still use the defaults.

Gnome Shell: 3.28.4

Ubuntu: 18.04.5 LTS

The system worked fine yesterday - but after starting it up again this morning, it just decided to fail on me. Endless loading screen, before it suddenly switches to a console view to show me this:

Everything is [ OK ], but the last two messages are:

[ 33.212602 ] usb 1-1: device not accepting address 3, error -101y server...p link was shut down...
[ 33.213252 ] usb 2-1: device not accepting address 3, error -110

I disconnected ALL USB devices (only a keyboard was attached). No change.

When trying to check /var/log/syslog, I read stuff like:

"Critical unable to create DBUS proxy for gnomeserver"

I tried switching to lightDM, no effect (I reach a login screen, but it freezes after a successful login just showing the background image and no GUI).

I went through about 30 threads with similar mentioned problems, I updated / upgraded all packages, removed gnome-screensaver, rebooted with older versions - nothing.

Any ideas? I can't find anything to try anymore - and I'm afraid to break it further.

The installation is only about half a year old, and besides using NGINX and php7.2, it is pretty vanilla. No major packages or alterations.

Edit 1:

Since a while now, I seem to have a weird problem: My laptop (with Ubuntu 14.04) randomly loses it's internet connection, at least 20-30 times a day (for about 1-2 minutes at a time) while the Network connection itself is completly stable (I'm using synergy to share keyboard & mouse, so I would quickly notice if the Network for my laptop was gone).

Now, the issue is: All other computers in the same network are fine (including aother machine with Ubuntu 14.04) and don't loose the internet connection. So it seems to be an issue with the ubuntu on my laptop, not the Network itself (or maybe the router, but I don't have access to it).

I already switched from Wifi to ethernet, disabling wireless, just to make sure that's not the problem - but it didn't help. When I manually restart the network-manager or disable/enable the ethernet connection over the UI, it works again instantly.

I'm not sure what kind of info can help out, but since lshw -C network is usually mentioned, here it is:

I'll add further information based on comments, of course.

I'm running in circles currently, trying to fix some mysql problem.

I couldn't use apt-get for a while now, because it always stuck at the line Setting up mysql-server-5.6 (5.6.27-0ubuntu0.15.04.1) ... and didn't let me do anything. So I tried to reinstall mysql, purging it. While I was able to remove mysql-server and mysql-client eventually, I'm still unable to purge mysql-common. Obviously, I managed to corrupt something, but how can I get my system back and running at this point?

My goal is to just get it back and running again (mysql).

I realize that there are many questions around here to answer that problem - but none seems to work for me so far.

I attempted:

sudo update-rc.d mysql defaults

This resulted in a locale error, which I fixed with How do I fix my locale issue? by altering /etc/environment

LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8

Now, by trying update-rc.d again, I get:

update-rc.d: warning: /etc/init.d/mysql missing LSB information
update-rc.d: see <http://wiki.debian.org/LSBInitScripts>
 System start/stop links for /etc/init.d/mysql already exist.

I found a suggestion on http://ubuntuforums.org/showthread.php?t=1313898 to use:

user@computer:/etc/init.d$ sudo update-rc.d -f mystartupscript remove
user@computer:/etc/init.d$ sudo update-rc.d mystartupscript defaults
user@computer:/etc/init.d$ sudo chmod +x ./mystartupscript

But do I risk to break my mysql implementation here? It's on a production server, so I can't just try it out and then suddenly be unable to start up mysql again.

In the end, the mysql server needs to run on startup. We had a few server restarts coming from the host, and everytime when that's the case, the database is not started and the hosted pages remain down until mysql is started manually.

Edit: /etc/init.d/mysql contents

I'm getting really frustrated with Ubuntu 14.04 at this point, after having to solve so many problems with it.

I use my current laptop at work, and there it seems to actually be able to connect over wired network properly. But as soon as I try the same at home, it fails - it doesn't seem to find any connection over eth0, my older laptop (with Ubuntu 12) does just fine with the same cable.

I realized that there are many questions about this issue already, with many similar / different solutions, and before writing this question I already tested many of them whitout success:

Things I tried, in any combination / suggested in other questions as solutions:

I tried sudo service network-manager restart, sudo service network-interface restart INTERFACE=eth0 and similar commands before and after edits - also rebooting the computer completly several times.

I edited /etc/network/interfaces, it currently looks like this:

auto eth0
iface eth0 inet dhcp

I edited /etc/resolv.cong and added nameserver 8.8.8.8

I edited /etc/hosts

I set managed=true in /etc/NetworkManager/NetworkManager.conf (then later, back to managed=false as it didn't seem to work)

I tried to set a fixed IP according to the MAC of my laptop on my router.

I cannot edit anything over the GUI, all options (Edit connections..., etc) are greyed out.

Edit: Added ethtool eth0 output as requested. Had to type it down by hand, now the link apparently doesn't work at work either (there was no change on my side, the laptop was shut down during the night, and it worked yesterday at work - now, I don't have any connection at all).

Edit 2: Added lscpi output

Now, here the /var/log/syslog and the ifconfig after a sudo service network-manager restart:

I'm trying to install ubuntu on a new T440p laptop from Lenovo and it always fails for the same reason:

[ 135.292409] SQUASHFS error: sb_bread failed reading block 0x9d7f3
[ 135.292411] SQUASHFS error: Unable to read fragment cache block [275faa28]
[ 135.292413] SQUASHFS error: Unable to read page, block 275faa28, size 23a7

I downloaded the newest Ubuntu (Ubuntu 14.04.1 LTS 64 bit), and now tried with every USB stick that I have, that has over 1GB of space, and no one works!

I checked the .iso file hash with HashCalc, and the hash is ok. I installed the files with Universal-USB-Installer, and that apparently worked too (I actually get the startup screen from Ubuntu, where I have to choose "start ubuntu" or "install ubuntu", etc) - but after 3 different USB sticks, and about 5 attempts, it still completly fails.

The ubuntu load screen simply loads for an eternity, and when I go to a virtual console with CTRL+ALT+F2, it shows the above error getting repeated each couple of seconds.

What can I do to solve this? Burning a CD/DVD is not possible atm, and I only have those three USB sticks to try (and it really doesn't seem like the USB sticks would be the problem).

Any Ideas?

Edit: I managed to burn a DVD now, and I still have the exact same issue! (I re-downloaded the .iso, checked it a second time, and the checksum again, seems to be ok). Even with the DVD, I'm getting:

[ 183.251602] SQUASHFS error: Unable to read fragment cache entry

and

zlib decompression failed, data probably corrupt

How is that possible?

I seem to have a larger memory leak on my current ubuntu System

After reporting strange Eclipse memory errors ( https://askubuntu.com/questions/148998/eclipse-constant-different-out-of-memory-errors ) I started to get 'Not enough Memory' error messages in my console today - while doing simple tasks like typing in sudo -s - or even - free -m

Typing in 'free -m' repeadetly showed me how my RAM quickly goes up from 700M to 900M, growing up to the size of 2000M in a few seconds (after freeing up memory with echo 3 > /proc/sys/vm/drop_caches )

Eclipse isnt the cause, I completly killed the process and the ram still was going up. Is there any way to detect where the leak is coming from? I cant even update my system anymore, since apt-get update fails (probably because it's out of memory)

Using Ubuntu 11.10

I'm getting really frustrated today, while trying to just set up my development environement and start doing some actual work.

After installing php, apache2 and mysql over apt-get install phpmyadmin I'm trying since about an hour, to make .htaccess files work in my /var/www/projectname/.htaccess

I tried out multiple solutions, that basically told me to edit /etc/apache2/sites-available/default but none of them seemed to work.

What I tried:

<Directory /var/www/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    #AllowOverride All
    #AllowOverride AuthConfig FileInfo Indexes Limit Options=All, MultiViews        
    Order allow,deny
    allow from all
</Directory>

The commented lines are what I tried, both didnt work. I either get a 500 internal error (when I set AllowOverride All) or the .htaccess doesnt do anything.

Can someone help me here? I need to get this to work, to finally start working :)

As side note, my knowledge with ubuntu or linux in common, is very slim - I just do what google tells me.
