@jamie: Agreed. To ensure that apparmor is not the problem, I installed the snap in classic confinement but got the same "stack smashing detected" error.
I believe the problem is that some libraries can't be accessed as indicated by the other error. I tried copying files libvlc.so.5 and libvlccore.so.9 from /snap/vlc/770/usr/lib/ to /usr/lib/x86_64-linux-gnu/ This one yields the same error: $ vlc VLC media player 3.0.6 Vetinari (revision 3.0.6-0-g5803e85) [0000000001b8b3b0] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. Qt: Session management error: None of the authentication protocols specified are supported *** stack smashing detected ***: /snap/vlc/770/usr/bin/vlc terminated Aborted But this one does not, but it does not start the vlc either (the program terminates without error): $ /snap/vlc/770/usr/bin/vlc VLC media player 3.0.6 Vetinari (revision 3.0.6-0-g5803e85) $ I think there might be other libraries that can't be accessed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1810027 Title: Snaps won't start - stack smashing detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1810027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
