Patricio, you need to allow the ptrace in your spotify apparmour profile. Adding this should fix it: ptrace (trace) peer=@{profile_name},
(taken from https://github.com/ruudkoot/spotify-apparmor ) I'm marking the bug as invalid, since the log spew is the result of a custom profile. ** Changed in: apparmor (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1424121 Title: Spotify apparmor="DENIED" operation="ptrace" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1424121/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
