Dear Maintainer,
I'm getting apparmor DENIED audit messages on the logs concerning thunderbird:

 audit[24604]: AVC apparmor="DENIED" operation="mkdir" profile="thunderbird" name="/run/user/1000/dconf/" pid=24604 comm="thunderbird" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000
 audit: type=1400 audit(1590141596.662:242): apparmor="DENIED" operation="mkdir" profile="thunderbird" name="/run/user/1000/dconf/" pid=24604 comm="thunderbird" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000

I keep showing the logs with:

and then I start thunderbird

Thanks in advance!

Reassigning to thunderbird, as it ships it's AppArmor profile itself.

We have this rule there:

owner /run/user/[0-9]*/dconf/user rw,

But it it does not handle the case when parent dir is missing. It does not reproduce in my KDE
desktop. Maybe you use some minimal desktop where Thunderbird is the first that deals with that
dconf stuff?

Anyhow, we should update thunderbird profile.

xiscu, could you please create `/etc/apparmor.d/local/usr.bin.thunderbird` file with this rule:

owner /run/user/[0-9]*/dconf/ w,

After that, restart AppArmor with `sudo systemctl restart apparmor`. Then, try starting Thunderbird
again, and see if that error is gone?

We believe that the bug you reported is fixed in the latest version of
thunderbird, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 961269@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
