Comment 33 for bug 1659988

@Thomas Mayer (thomas303)

I previously reported (on another page from where I was pointed here) this problem in Ubuntu 12.04.5 LTS. Following suggestion I took the full profile version 7. I did confirm that the problem was apparmor. However with usr.bin.firefox_patched it began throwing parser errors one line at a time.
Without really understanding I began making these mods:
------
17,19c17,18
< #include <abstractions/dbus-strict>
< #include <abstractions/dbus-session-strict>
< #include <abstractions/dconf>
---
> #include <abstractions/dbus>
> #include <abstractions/dbus-session>

< #include <abstractions/ubuntu-unity7-base>
< #include <abstractions/ubuntu-unity7-launcher>
28d24
< #include <abstractions/dbus-accessibility-strict>
------

On the next run there was a complaint about TOK_* things, none of which can be found recursively in my /etc/apparmor.d.

That's where I left it.

I looked at a different platform running Ubuntu 14.04.5 LTS, where Firefox 51.0.1 was updated through apt without problems. But on this platform apparmor is disabled. I did not do that, so I assume that it was shipped with the two symlinks in /etc/apparmor.d/disable. Possibly that was done with a previous update. On that platform I notice a 2014 datestamp on usr.bin.firefox.

I suspect that a substantially different usr.bin.firefox is needed for 12.04 LTS.

Thanks.

Thanks for your help.
