First, I think app armor was blocking the fog update, so I disabled all of apparmor, but it still didn’t work and I got the same error about apparmor in the logs still. So I dug deeper and disabled it further and/or removed it.
Then, it still didn’t work, so I looked at the logs some more. I made sure apache was working and fixed a few things there. I also made sure mysql was working.
I tried a lot of other things, but I think this mysql upgrade with my root user and root password is what was really needed. I had to do the mysql update manually with my own command instead:
sudo mysql_upgrade -u root -p
Then, I re-ran the fog update and it worked. If that doesn’t work for anyone else, let me know and I can give you more details on other things I did to fix it. It is all working now. Thank you! Fog is awesome!
BOTTOM LINE = Follow the errors in the logs. I did sudo journalctl -xe a lot and also tail -n 20 /var/log/mysql/error.log to see what was going on.
