Thanks Etienne, this is a bit surprising! Do I understand correctly,
that on the slower machine (where you are seeing this bug) you will not
be able to start firefox until you have run that apparmor_parser
command? Not even if you try starting firefox well after the login?
It's strange, because your logs show that the apparmor.service unit was
started can you please also attach the output of these commands:
sudo systemctl status apparmor
sudo journalctl -b _SYSTEMD_UNIT=apparmor.service + SYSLOG_IDENTIFIER=audit
And then also this (make sure you haven't previously started firefox in
this boot):
SNAPD_DEBUG=1 firefox
And after that, let's have a look at the full system log (I have no
clear idea what to look for, actually, but maybe I'll spot something
suspicious):
sudo journalctl -b

Bug description:
Per discussion with Zyga in #snapd on Freenode, I have hit a race
condition where services are being started by the system before
apparmor has been started. I have a complete log of my system showing
the effect somewhere within at https://paste.ubuntu.com/p/Jyx6gfFc3q/.
Restarting apparmor using `sudo systemctl restart apparmor` is enough
to bring installed snaps back to full functionality.
Previously, when running any snap I would receive the following in the
terminal:
---
cannot change profile for the next exec call: No such file or directory
snap-update-ns failed with code 1: File exists
---
Updated to add for Jamie:
$ snap version
snap 2.44.2+20.04
snapd 2.44.2+20.04
series 16
ubuntu 20.04
kernel 5.4.0-21-generic
