[Bug 1926919] [NEW] redshift apparmor settings not quite correct

[StoatWblr]

Public bug reported:

redshift isn't starting because apparmor is blocking it from starting.

(DENIED opening ~/.config/redshift/redshift.conf mask r)

it worked ok in 20.10 and 20.04

This looks like a security oversight


There are a couple other apparmor oversights showing in dmesg (cups-browsed, ntpd)
