Hello @8836290, no Proton log hints that something went wrong before Proton itself had a chance to run. If you completely close Steam, then run steam from a terminal, are there any hints in the terminal spew when you tell Steam to start one of those games?

Also, please copy the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put it in a gist, then include a link to the gist in this issue report.

Please give #586 a read for the majority of the issue you're seeing.

Please give #586 a read for the majority of the issue you're seeing.

So if I understand by reading #586 do I have to uninstall the snap version of steam and just download and install the.deb version and try this one?

Yes please. If that solves the issue, please report it to https://github.com/canonical/steam-snap.

The key log line seems to be this:

bwrap: Can't bind mount /oldroot/media/myrmidon/Linux Games/Steam Library/steamapps/common/SteamLinuxRuntime_sniper/var/tmp-9T0171/usr on /newroot/usr: Unable to mount source on destination: Permission denied

This is a fatal error for the container runtime: if Snap will not allow us to do the setup that the container runtime requires, then there is not really anything that the container runtime can do to resolve that.

@kisak-valve, perhaps you could retitle this to something like:

With Steam as a Snap app, cannot run Proton games with Steam library in /media

to avoid this issue being mixed up with other issues with the same symptom?

This is likely to be "won't fix" (or more accurately "can't fix") unless someone from Canonical can help.

I installed the .deb version and steam site and the games run properly now. Thank you. I think we can close this issue as solved here.
