Why don’t you just start onionshare from the application menu?

#2 Updated by scootergrisen 2019-02-03 22:12:30

OnionShare in the application menu runs onionshare-gui.

The .desktop file says:
> Exec=/usr/bin/onionshare-gui

If i select OnionShare in the application menu i see this with “sudo dmesg”:

I won’t have time to look into this soon unfortunately. But putting it on my radar anyway.

If you got some ideas on what i could try to get closed to what the problem might be i could try that in the mean time.

This seems to be a bug in the AppArmor profile we ship. It seems it’s been upstreamed but is not shipped in the Debian package yet (see Feature #11929#note-15) so let’s fix it on our side for now. I’ll check if the problem is in an abstraction.

At first glance, it looks like /etc/apparmor.d/abstractions/base expects all shared libraries to be called lib*.so, while this one is called VBoxOGL.so.

Pinged on the upstream discussion. I don’t expect we’ll reach a conclusion that we can implement in time for 3.13.

It seems that consensus was reached upstream. I’d rather resolve the conflicts of the proposed fix with our config/chroot_local-patches/apparmor-aliases.diff only once, so my plan is:

  1. get this merged upstream
  2. apply the fix in Debian, batch this with other bugfixes and get this unblocked for migration to Debian testing; I’ll try to do this at the BSP at the end of March
  3. once it’s in Debian testing, feature/buster will FTBFS and I’ll have to resolve the merge conflict

#16 Updated by CyrilBrulebois 2019-04-02 10:49:49

I think I now understand what the current (in feature/buster) patch does, but I’m not sure how to forward these changes with the new apparmor code (as of 2.13.2-10).

I’d be happy to get from you an updated hunk for the /etc/apparmor.d/abstractions/base file…

I’ve done one of the possible conflict resolutions and will push once I confirm it at least fixes the FTBFS. Then our test suite should tell us if my conflict resolution breaks stuff.

CyrilBrulebois, hefee I’ve pushed a candidate conflict resolution that allows the build to reach the next failure (Bug #16604).

What this ticket was about has been fixed on feature/buster. Please file a new, dedicated ticket if I got the merge conflict resolution wrong :)
