After upgrading my system from Ubuntu 18.04 to 20.04, I had some graphical glitches and had to reinstall xorg (following this answer). Everything seemed to work fine, except that I could not launch Steam anymore. I tried reinstalling Steam, including removing all the Steam related folders in /home, but to no avail. First time booting Steam after reinstall, a window with a progress bar pops up stating that "Pins potentially out of date ... rebuilding" and then nothing. All other times, there is no graphical feedback whatsoever.

The terminal output at first glance does not seem to point towards any missing packages or anything either, so I am out of ideas. Most of the related reports I find online turn out to be related to proprietary graphics drivers of dedicated GPU's (typically NVidia), but I only have an integrated Intel chipset and want to play some indie games

  • It is just a shot in the dark. ubuntu12_32 smells like a 32bit binary. maybe you need the 32bit libraries and they got removed with the update? You could try to use ldd on this binary and see which libraries it uses and check if they are present. Do ldd <full path to binary>

  • @nobody I already tried renaming all the folders several times, Steam just keeps rebuilding them on first run

  • Maybe you need to sudo dpkg --add-architecture i386, then update drivers sudo ubuntu-drivers install, or remove cache mv ~/.cache ~/.cache_backup. Nov 19, 2020 at 19:23

So, I came from an older install of Ubuntu and kept Unity desktop. I tried literally every answer that I could find on stack and on ubuntu forums, to no avail-- Finally, I installed gnome and logged into a gnome session and guess what STEAM STARTS. I haven't tested if gnome being present or being logged into gnome makes the difference. My guess is that steam client expects gnome on 20.04

  • Weird! Glad to hear you found a solution. Unfortunately I am no longer able to test this solution; I lost patience and reinstalled Ubuntu 20.04 from scratch.
