I am trying to install top tracker provided by Toptal. I am getting this error

*sudo dpkg -i ~/Downloads/toptracker_1.6.2-6524_amd64.deb

when I tryed to install libappindicator1 then getting
sudo apt-get install libappindicator1
Reading package lists... Done

Reading state information... Done
Package libappindicator1 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libappindicator1' has no installation candidate

Can anyone let me know how to fix this ?

I recently upgraded to 24.04. display resolution is on minimum settings and I cannot change it. Also everything is so slow, so I tried to install amdgpu-install --usecase=graphics with latest version found here https://repo.radeon.com/amdgpu-install/latest/ubuntu/noble/. This did not work and gave errors. Then I switched from 6.8.0-45-generic to the older kernel version 6.8.0-40-generic as it is the latest hwe kernel for 22.04. amdgpu-install --usecase=graphics finished without problems. But after rebooting I still have the same problems. Has anyone gotten the GPU driver to work on 24.04?

I am setting up a server, and I was wondering where to modify global PHP settings. I see there is a dir /etc/php/8.3/fpm/ with several files and folders inside.

I am trying to do this because I need to change PHP options like memory_limit, upload_max_filesize and date.timezone.

Nginx 1.26.2 / PHP 8.3.11

This works..

xdotool search  "Mozilla Firefox" windowminimize

but this does not minimize my Terminal.

xdotool search  "Terminal" windowminimize

Why isn't my Terminal being minimized?

This question is an obvious updated version of How do I remove a malformed line from my sources.list?. In Ubuntu 24.04 and later Ubuntu software sources have been moved to /etc/apt/sources.list.d/ubuntu.sources. The objective of this question is to get at least one updated answer that is suitable for merging into the original canonical question.

As a starting point here is what the default ubuntu.sources file looks like in Ubuntu 24.04.
