So, the error was related to passt, not apparmor. This is because it uses an incorrect rule in abstractions/passt.
By design, rules containing some options, such as runbindable, cannot include a source. I just sent the following patch for passt that should solve your issue https://archives.passt.top/passt- dev/20240517115053.53072-1-maxime.bel...@canonical.com/T/#u , i.e. you need to modify `mount options=(rw, runbindable) /,` in /etc/apparmor.d/abstractions/passt to `mount options=(rw, runbindable) -> /,` That being said, I will probably send a merge request to apparmor so that if in similar cases the source is '/', mount does not fail, thereby preventing similar future errors. ** Changed in: apparmor (Ubuntu) Status: New => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065685 Title: aa-logprof fails with 'runbindable' error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2065685/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
