[pkg-apparmor] Bug#968387: apparmor: Broken printing and printer autodiscovery

[user]

Package: apparmor
Version: 2.13.2-10
Followup-For: Bug #968387


With the printer found and printing not functional:

# tail /var/log/cups/error_log
E [20/Aug/2020:16:33:13 +0200] Unable to open listen socket for address [v1.::1]:631 - Permission denied.

# journalctl -kaf --no-hostname | grep -w 'apparmor="DENIED"'
ago 20 16:35:49 kernel: audit: type=1400 audit(1597934149.904:2054): apparmor="DENIED" operation="create" profile="/usr/sbin/cups-browsed" pid=825 comm="cups-browsed" family="unix" sock_type="stream" protocol=0 requested_mask="create" denied_mask="create" addr=none


I cannot recreate the other case where the printer was not found at all.

This is not related to lxc (this machine has no containers yet) except that it recommends apparmor.
