Comment 3 for bug 1850013

I just look through those files they are all empty.

I disabled that apparmor profile, like this

sudo ln -s /etc/apparmor.d/usr.bin.certspotter /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.bin.certspotter

If you can tell me how to re-enable this profile correctly, I try to see if the error still exists? and get you those log file hopefully with something inside.
