Ubuntu – Steam browser doesn’t work and games can’t be installed

I managed to get the download started, browser is still not working but at least it installs the game.

Following procedure:

Install if you haven't so far, the Linux Steam Version and make sure it works.
open this file with your favorite text-editor: ~/.steam/steam/config/config.vdf
search for "CS" and copy the entire line
paste the line after the line starting with "cis" in file: ~/.wine/drive_c/Program Files (x86)/Steam/config/config.vdf

or wherever you installed steam and restart.

Updates – How to Stop an Individual Snap from Updating in Ubuntu 22.04 LTS

To your general question, "How to stop an individual snap from updating Ubuntu 22.04 LTS", the answer is, as you also found out: you can't. There is little user control on snap updates - they update automatically and that cannot be stopped. That is one of the criticism about snap.

To your specific question with respect to Firefox snap being installed on an update, it is actually the firefox APT package of Ubuntu that is being updated. That package triggers an install of the snap version. There are many tutorials out nowadays on how to replace the snap version by a .deb version from a third party repository.

For updates of APT packages, there is a lot more control. The installation of the Ubuntu version of firefox specifically could be prohibited with following APT preference:

cat <<EOF | sudo tee /etc/apt/preferences.d/firefox-no-snap.pref
Package: firefox*
Pin: release o=Ubuntu*
Pin-Priority: -1
EOF

This creates a configuration file /etc/apt/preferences.d/firefox-no-snap.pref that instructs APT to forbid installing the firefox .deb package of the default Ubuntu repositories. Thus, the snap version of firefox only can be installed manually by the snap install firefox command. A firefox package from another source could still be installed.

There are many tutorials to be found on how to replace the snap Firefox by a deb version. All involve configuration changes to APT, either by promoting the priority of firefox from a third party PPA, or demoting the priority of the default Ubuntu package.
