I installed Ubuntu 25, version:

Linux version 6.14.0-15-generic (buildd@lcy02-amd64-022) (x86_64-linux-gnu-gcc-14 (Ubuntu 14.2.0-19ubuntu2) 14.2.0, GNU ld (GNU Binutils for Ubuntu) 2.44) #15-Ubuntu SMP PREEMPT_DYNAMIC Sun Apr 6 15:05:05 UTC 2025

I like the fast response and performance of Ubuntu 25 so the ideal solution would be to stay on this installation. I know that on the prior version, Ubuntu 24 it worked.

I installed Steam again, mounted my steam folder drive and added the steam folder as the default installation directory.

Then I started CS 2 and got this error. (see picture)

What I already did:

• Installed files > Verify integrity of game files
• Installed files > Move install folder > Moved the folder to the same disk where Steam app is installed
• Installed DLC > Counter-Strike 2 Workshop Tools
• Delete the cs2.exe (…/game/bin/win64/cs2.exe) and all .signature files in this folder
• Delete parts of the game folder (…/game/bin)
• Checked integrity again
• Removed CS2 completely from steam and re-downloaded it

Nothing seems to help. What can I do to make VAC be quiet again?
