I want to upgrade Ubuntu from 20.10 to 21.04. When I type do-release-upgrade -d, I get a message "Please install all available updates for your release before upgrading." I have one package held back, specifically xserver-xorg-core. I do not want to upgrade this package because of a bug it has, I need to continue using an older version. How can I still upgrade Ubuntu?
I created a package for Launchpad PPA and want to upload it to Launchpad. I've used dput command and this is what I get:
tomica@home:~/Desktop$ dput ppa:{MY_LAUNCHPAD}/ppa packagename_0.0.1_source.changes
Uploading packagename using ftp to ppa (host: ppa.launchpad.net; directory: ~{MY_LAUNCHPAD}/ppa)
running supported-distribution: check whether the target distribution is currently supported (using distro-info)
{'allowed': ['release'], 'known': ['release', 'proposed', 'updates', 'backports', 'security']}
running required-fields: check whether a field is present and non-empty in the changes file
running checksum: verify checksums before uploading
running suite-mismatch: check the target distribution for common errors
running check-debs: makes sure the upload contains a binary package
running gpg: check GnuPG signatures before the upload
Uploading packagename_0.0.1.dsc
Uploading packagename_0.0.1.tar.gz
Uploading packagename_0.0.1_source.buildinfo
Uploading packagename_0.0.1_source.changes
tomica@home:~/Desktop$
I would think that this means my upload was successful. However, when I visit my PPA, it's empty. Why is that?
If I try to upload my package again, this is what I get:
tomica@home:~/Desktop$ dput ppa:{MY_LAUNCHPAD}/ppa packagename_0.0.1_source.changes
Package packagename was already uploaded to ppa
If you want to upload nonetheless, use --force or remove packagename_0.0.1_source.ppa.upload
tomica@home:~/Desktop$
This means that my package should be visible and accessible, but it isn't. What am I doing wrong?
Some app icons (but not all) in some icon themes are not being detected/used. For example, if I select Faenza icon theme, icons for Terminal, Rhythmbox, Files and some others seem to not be from Faenza theme, but some other:
This is strange because I know for a fact that Faenza does contain icon files for these apps, and also this problem has not existed in the previous versions of Ubuntu (<20.10). The same problem happens with Numix theme.
On the other hand, Numix Circle seems to not suffer from this problem:
I've had a similar, but not identical, question before. The work-around from that topic does not help now.
How can this be fixed?
I have a 2019 Dell XPS 13 2-in-1 7390 connected to Dell D6000 docking station and using Dell SE2719HR secondary monitor. The dock uses DisplayLink technology, for all it matters. My Ubuntu version is 20.04.
When I enable Night Light, it is only displayed on the laptop's built-in monitor. Even when I close the lid (which turns off the built-in monitor), Night Light still isn't displayed in the external monitor.
I've tried mirroring displays, extending displays, setting external display as only one active, nothing helped. I went through this topic here and all suggested solutions, none helped either.
Is this a bug of some sort, or am I doing something wrong?
Last year I bought Dell XPS 13 2-in-1 7390. I bought it with intention to install Ubuntu Linux. To my sorrow, it turns out that Ubuntu was not supported on that model. Specifically, here are the problems I realised:
This year, Dell released a Dell XPS 13 9300 Developer edition with Ubuntu pre-installed on it. By comparing the configurations, I've discovered that the new Developer edition XPS 13 has exact same components as my 2-in-1.
My questions are:
I'm using Faenza icon theme on Ubuntu, specifically its Faenza-Darkest version for dark backgrounds (such as Ambiance theme). After upgrading from 18.04 to 19.04 some icons seem broken. Please see the screenshot:
Instead of beige folder icons, I get these dull grey ones. I tried re-installing Faenza, but its PPA seems to be down and Faenza is missing from the official Ubunbu PPAs.
How can I fix my icon theme?
I've been using Docky for almost 10 years. Yesterday I upgraded Ubuntu to 19.04 and to my surprise I realised that during the upgrade Docky got removed. I tried adding Docky PPA again, but got the message that Disco distro is not supported. I tried manually installing Docky from a .tar.gz package, but I keep getting infinite dependency errors, last one being:
configure: error: Package requirements (gconf-sharp-2.0) were not met:
No package 'gconf-sharp-2.0' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.
Alternatively, you may set the environment variables GCONF_SHARP_20_CFLAGS and GCONF_SHARP_20_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
What on Earth is going on here? How do I install Docky back again?
I'm trying to install Xdebug on Ubuntu Zesty (17.04), but am having trouble resolving dependencies. I'm following instructions from this url:
Point 4. there says "Run: phpize (See the FAQ if you don't have phpize." When I do, I get the following error:
The program 'phpize' is currently not installed. You can install it by typing: sudo apt install php7.0-dev
I don't know why php7.0-dev is offered, my PHP version is 7.1. So instead, I tried installing php7.1-dev. Then I got this message:
php7.1-dev : Depends: libssl-dev but it is not going to be installed
Finally, if I try installing libssl-dev manually, this is what I get:
libssl-dev : Depends: libssl1.0.0 (= 1.0.2g-1ubuntu11) but 1.0.2k-1+deb.sury.org~yakkety+1 is to be installed
How do I resolve this problem?
On my two laptops running Ubuntu 16.10, each time they go to sleep, or after the screensaver (i.e. Ubuntu's default screen turn off), some tray icons are missing their images. I mean, the placeholder is there, but the image is missing. I'm attaching an image:
For reference, here's how it should look like:
This far I've noticed the problem exists only with Skype Alpha and Team Viewer icons, whereas all others seem to work fine.
Not sure if it's relevant, but I'm using Arc GTK theme with Faenza icon theme.
What ever could be causing this?
I have several partitions on my internal HDD. When I open a Nautilus window (any folder), the mounted partitions are not showing in the window's sidebar. This happened after I installed Ubuntu 16.10. Before that I was using Elementary OS without Nautilus.
The same problem exists on my guest account.
If I enter in Terminal sudo nautilus then all the partitions do show up in the sidebar, although some show their UUID instead of Label.
While trying to resolve this, I've modified my /etc/fstab several times (both manually and through Disks app), but without success. Every time the result is be the same - no partitions in the Sidebar.
An additional question, not sure if it's related, if I open Disks app, edit any partition's Mount Options and set Automatic Mount Options to On, that partition does not automatically mount. This is not the case on my other computers. Could it be in any way related to my problem above?
As I said, I've modified my /etc/fstab a few times already, but here's how it currently looks like:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

Edit: So muru suggested that my question is a duplicate of this one. I've tried both answers from that question and neither worked unfortunately.
I've also tried Byte Commander's suggestion from his comment, i.e. commented out all partitions from /etc/fstab and restarted my computer (twice) and that didn't work either. Any new suggestions are much appreciated.
Edit 2: As advised by user.dz, I'm adding here outputs of the following commands:

I've been using for years my own custom made keyboard layout. It's fairly easy to create and use a new layout. However I frequently reinstall my system and each time I do, I need to add my custom layout again and again.
I want to know is it possible to keep my files somewhere safe, for example, under my /home dir, instead of /usr/share? Ideally, I would love to be able to create only two files
~/.xkb/rules/myevdev.xml
~/.xmb/symbols/my_lng
and then have Xkb pick them up somehow. Here are my questions:
evdev.xml file to my /home dir and then add my rule in it, or can I keep it clean and only have it contain my rule and no other (and have Xkb somehow integrate it with the existing /usr/share/X11/xkb/rules/evdev.xml)?.deb installation for my custom layout, what would be an ideal file and folder structure in this case? Where could it be installed so as not to affect the system files and not get overwritten during an upgrade/reinstall?So far I've tried fiddling with the setxkbmap, but nothing seems to work the way I'd expect. I tried setting the -rules option, but my file isn't detected.
Thanks in advance.
On my work computer I've noticed that some icon-theme.cache files are very large. For example:
/usr/share/icons/hicolor/icon-theme.cache: 120MB/usr/share/icons/gnome/icon-theme.cache: 113MB/usr/share/icons/pacifica/icon-theme.cache: 103MB/usr/share/icons/oxygen/icon-theme.cache: 94MBetc. What could be the reason for this? For example, on my home computer, /usr/share/icons/hicolor/icon-theme.cache is only 24kB big, and others are even smaller than that.
Can I delete these files (will they auto-regenerate)? Or is there any other way to shrink them?
I've read recently that the 16.04.1 update was made public last week. There it says that users of 16.04 should only run the usual system update to receive this upgrade. However I'm not receiving this update at all. I tried with GUI Software Updater as well as Terminal commands sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade, to no avail. I've changed the update server from Main to US and back to Main again, no effect. I've changed settings from Any new version to LTS only and back to Any new version again, still nothing.
I would like to know, if I'm not receiving the upgrade, what could be the reason for that, and also how can I make 100% sure that I'm running 16.04 and not 16.04.1? In System Details I can see it says Ubuntu 16.04, does that mean that it's definitely not .1?
I want to completely, unconditionally remove all icons from Unity Launcher, so that no icons are ever displayed there. For that, I found out that dconf setting with the key of com.canonical.Unity.Launcher favorites needs to be emptied. However, when I do try to delete its value, whether through dconf-editor, or with the following Terminal command:
gsettings set com.canonical.Unity.Launcher favorites '[]'
the value always reverts to the default value of:
['unity://running-apps', 'unity://devices']
Is there a way to leave this key's value empty, i.e. []?
If yes, how can it be done? Also, are there any potential or known negative effects to it?
The reason why I want to do it is because Unity Launcher conflicts with my dock app (Docky). The problem has been reported numerous times since 2012, but sadly there are no indications that it will ever get fixed. That's why I'd like to remove all indicators (icons) and thus stop all activity in the Launcher, if possible.
I've noticed that many icons are missing in my folder view, but have no idea when or how this happened. Here's the screenshot:
The icons that are missing are those from the sidebar and navigation bar, they are shown as a red missing sign on black background.
Any ideas how this happened and how to fix it?
Is there a way to change the partition format from FAT32 to NTFS without losing data in it?
For now I am aware of one method: split partition in two, set the new partition format to NTFS, copy data to it, then delete the old partition and add its space to the new one. One fault with this method is simple: it can't be done if more than a half of the current partition is already used.
So I'm looking for a solution that wouldn't delete my data, and just change the partition format from FAT32 to NTFS. Is something like that possible or not?
I've upgraded to Raring last night. The upgrade itself went okay, no errors. But when I rebooted the computer afterwards and logged in to my Unity session, all I could see was the Desktop background (together with Desktop icons), and no Unity interface. The Super button shortcut wasn't showing the Dash, there was no top panel etc. Please see the screenshot.
As a hint, I'm suspecting it's got something to do with my switchable graphics. I'm running Ubuntu on Acer Aspire AS5830TG with nVidia GT540M and an Intel integrated card. In 12.10 I was using Bumblebee to manage the graphic card switching. During the upgrade I saw something related to nvidia had to be uninstalled, but didn't pay much attention to it. I can't be sure if it has anything to do with my problem though.
What could possibly go wrong?
I just got an idea to create a lense that would work as a Character Map. I need character copying very often, and on Windows there was a very useful programme (PopChar), but on Ubuntu I haven't found anything like it. So I thought I could try to build a lense that could copy a single character (or perhaps a sequence of characters, if possible?) by just searching for it in the Dash and clicking on it once found. Since I've never done anything similar, I'm not sure how possible it is to copy certain content by clicking on its visual link in the Dash.
So, my question is, if I create a Lense + Scope for copying Unicode characters, would it be possible through Dash to just copy a character that I click on once I find it?
It might sound stupid, but I don't know how to browse files on my device (phone) connected to Ubuntu machine via Bluetooth. I see that the connection is established, I can send files from my computer to the phone, but just can't seem to find how to browse the phone's file system.
I should mention that my Bluetooth adapter is Foxconn / Hon Hai, which hasn't been supported in Linux until recently. However, now I'm able to pair my phone with the computer, and to send files from my computer to the phone. What's not working is sending files from the phone to the computer and browsing phone files on the computer.
The reason why I'm asking this question is actually to check whether my Bluetooth adapter is still not fully supported, or I just don't know how to use it properly.
I'm seeing this unwanted behaviour eversince Unity came to Ubuntu. The Unity's Launcher randomly "steals" the endpoint for the minimizing animations from Docky. In other words, when I click on an icon in Docky to minimize a window, that window minimizes to Unity instead of Docky. That happens most of the time to all of the windows, although sometimes, also randomly, it happens that the windows minimize to Docky, but very rarely.
Here's how it looks when I minimize a window:
Here's how both animations should look:
