I tested and still use x86/i386/32-bit hardware.
post-18.04 and i386
Releases occurred for Lubuntu 18.10 & Xubuntu 18.10 and they were supported the full life of the cosmic cycle.
ISOs were released into the disco cycle too (Lubuntu, Xubuntu), so any installs made with those were provided updated packages the entire life of the product, however both ...

You can do that using the pactl command.
First: List the audio devices using
pactl list short sources
Second: To set a default output device run the command
pactl set-default-sink <'output_device_name'>
Example: pactl set-default-sink 'alsa_output.pci-0000_00_1f.3.analog-stereo'
Now that the device names are known, and they have been verified to work ...

Your system misses mktemp executable as stated in below snippet:
/var/lib/dpkg/info/tex-common.postinst: 117: mktemp: not found
Install it with:
sudo apt-get install coreutils
And then resume installation of texlive by:
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt install texlive-full

You missed d while installing the package, i.e., tftp-hpa is TFTP client while tftpd-hpa is the server.
If you run apt show tftp-hpa and read description, you'd see
Description: HPA's tftp client
Trivial File Transfer Protocol (TFTP) is a file transfer protocol, mainly to
serve boot images over the network to other machines (PXE).

I am not sure if the specific goal is to know the nested loop operator behavior, or to find the bootvolume, but in your shoes I've solved that problem in the past avoiding the nested while loops since I find them confusing to read and maintain:

if df $disk | grep '/boot'; then

I still don't know why that original issue (time reset back to wrong time) has actually happened but I could get my time finally working by uninstalling ntp (sudo apt-get remove ntp) which automatically installed and configured systemd-timesyncd instead so that all my system times finally set themselves to the correct setting:
Still asynchronous after ...

That software has not been updated since 2016 according to their web site.

However each additional user (that is created later using the KDE system settings) isn't member of the same groups
This is normal and the default for all Ubuntu flavors. By default regular users do not have permissions to make changes to hardware/configuration files and are given write access only to their own home directories. This is by design.

The toggle-shade shortcut is not enabled by default and is not accessible using Keyboard Shortcuts.
In order to reset it to its default setting (no shortcut), you can run the following gsettings command:

There is also a graphical way to reset it using dconf-editor:

These days, a new group is created for every new user. The group has the same name as the user and only that one user as member. The first user account is special; it is added to more groups because that one is considered to be the primary user of the machine, so that user gets permissions to use all kinds of hardware or virtual machines etc.; but that is ...

I had the same problem with the network being offline after an update on Ubuntu 20.x.
I found this bug report: https://bugs.launchpad.net/netplan/+bug/1922898
Here is how I was able to fix my Ubuntu 20.x servers:
Download latest netplan.io_0.102:

Here is a low-level answer. It might need further refining if it is not exactly what you are looking for, but I can hardly help you more as I have only one GPU on my laptop.
First identify the PID (process ID) of your OpenGL program.
/proc/PID/fd is a directory that lists the files your program has opened. If you ls -l that directory, you will see files like ...

Zoom is difficult to close
The close button ❌ on the top right corner of the Zoom window does not actually close the app. It minimizes the app and removed the app icon from the Dash/Dock (the left panel in Ubuntu). Normally Zoom icon in the system-trey/app-inidiator (top panel) would alert you that Zoom is not closed and close Zoom from there. However, a bug ...

I saw this got an answer on Discourse, but I thought I'd share what I found.
Adding cloud-config-url=/dev/null to the kernel arguments does prevent cloud-init from downloading the ISO, and the ISO is only downloaded once. The full grub line is now

The Ubuntu 20.04 inside the virtual machine won't actually be aware of your laptop's display (it is actually using a "virtual" display). That's why it can't control your laptop's screen brightness.
If you test Ubuntu 20.04 with a Live USB (without installing) you should be able to see the brightness slider, or use your laptop's function keys to ...

If you delete the network: section from your autoinstall config, then a network config will be generated automatically. This might suit your needs.

How much free space do you have on the C: drive? The fact that, as N0rbert points out, mktemp isn't installed, along with the multiple No apport report written because MaxReports is reached already messages, seems to indicate a problem with free space.
Also check whether any portion of C: (especially in C:\Users\) is compressed or encrypted. If the virtual ...

You were missing the use of xdg-mime on a specific file.
How can I see actual mime type?
Try
$ xdg-mime query filetype index.ts
or
$ mimetype index.ts
It seems file examines the contents of the file, while xdg-mime uses a combination of methods to determine the MIME type, including some times calls to file.
I didn't find so far a specification of the ...

Turns out somehow the UUID of my swap partition which is /dev/nvme0n1p9 here, got changed. I installed gparted to check the UUID of my swap partition (/dev/nvme0n1p9), changed it in the /etc/fstab and now the booting process works fine and takes about 5-6 seconds.

I also had this problem with the distribution version of FreeCAD 19. It does appear that because this is a snap package with its own virtual environment it cannot access 'normal' file system installations such as graphviz.
Running the AppImage instead of the distribution version allowed me to access the Dependency Graph which requires graphviz in FreeCAD.

Miracast (or Wi-Fi Display) is the relevant technology here. Your Microsoft adapter acts as a Miracast sink, while Ubuntu should act as a Miracast source, so you can mirror your laptop display on your monitor screen wirelessly.

You can test it on Ubuntu 20.04, but it ...
