I think that the problem is that 32 bit architecture is not enabled by default in Ubuntu 20.04. Steam uses 32 bit libraries, for that, it crashes randomly.
After use this command and update Ubuntu with last updates, the system is more solid and is not crashing all the time: dpkg --add-architecture i386; apt update This solved my problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897395 Title: Ubuntu Crash constanly after last patch update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1897395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
