Deb on Ubuntu 22.04 (Not a Snap) – OMG! Ubuntu! (.uk). That process is outlined here: How to Install Firefox as a. I ended up finding an article to revert back to the way Firefox was installed in Ubuntu 20.04. I tried a couple of different troubleshooting steps, such as moving the policy file to /etc/firefox/policies, changing file permissions, moving the certificate file, but wasn’t able to find a quick path to resolution.

Ubuntu 22.04 switched to a newer snap installer for Firefox and this change had an impact on both of these settings. Additionally, in a previous article ( ) I had described a process to create a Firefox policy to install a specific CA certificate used in my lab. In the previous Ubuntu 20.04 article, I updated a file ( /etc/dconf/db/local.d/00-favorite-apps) to pin Firefox to the app list in the GUI. I spent more time troubleshooting Firefox than I care to admit. This resulted in appending an additional couple of lines to the /etc/sssd/nf file that were not in my previous notes, but are captured in the official documentation. The Horizon documentation has since been updated ( ) and provided better guidance for SSO. At that time documentation was a little light on how to make this work with Horizon. When I last created this desktop, I switched from PBIS Open to SSSD for Active Directory authentication. I followed the process from a similar article I created for Ubuntu 20.04 ( ) and found only a few minor differences. I decided this would be a good opportunity to build a new image that revved to the next major release. This is the current/newest Long Term Support release ( ), which support going into early 2027. It had been several months since I had last updated the desktop and realized the Ubuntu 22.04 had since been released. I recently wanted to apply some updates (OS updates and Horizon Agent) to my Ubuntu 20.04 desktop.
