Comment 11 for bug 1620771

@Terry,

Did you reload the profiles? In particular, you need to reload /etc/apparmor.d/usr.lib.snapd.snap-confine and /var/lib/snap/apparmor/profiles. Eg:

sudo rm -f /etc/apparmor.d/cache/usr.lib.snapd.snap-confine /var/cache/apparmor/snap.*
sudo apparmor_parser -r /etc/apparmor.d/usr.lib.snapd.snap-confine /var/lib/snapd/apparmor/profiles/*

(or reboot after removing the cache files).
