[Bug 1756800] Re: Failed to start AppArmor initialization with status=123/n/a

[Seth Arnold]

Ron, you look at the profiles that failed to compile/load in the
journalctl -u apparmor output, and decide what to do with those profiles
-- if they are for programs that no longer exist because the package has
since been removed, you can just delete the profile file. If they are
for programs that you use, then you should fix whatever error is in the
profile.

More details would require more details. Consider filing a new bug if
you've got this error with profiles that were provided by a package.

Thanks

  journalctl -xe gives essentially the same lack of information issued after a systemctl restart apparmor.service.
