Greetings, I'd like to mention that hoxp18 (and I) encountered the bug not when activating these extra profiles, but when we used aa-genprof on completely unrelated programs. In other words, it (probably) affects anyone who uses aa-genprof and has the apparmor-profiles package installed, not only users of these profiles.
I suggest putting an extra '#' before the line responsible for inclusion of the local profile, making that line a comment — same to the approach in /usr/share/apparmor/extra-profiles/usr.lib.firefox.firefox . A little more conjecture (could be wrong): I guess the whole thing is that aa-autodep (and aa-genprof) scans all the profiles under /usr/share/apparmor/extra-profiles , which is the "inactive_profiledir" defined in /etc/apparmor/logprof.conf , and exits with error when it encounters a line that includes a non-existent <local/XYZ>. Kind regards, miteigi
