Apparmor won't start after apt upgrade. Ubuntu server 18.04

[cookie505]

I am running Ubuntu server 18.04. It's just a web server with apache and PHP. I just updated everything. After I restarted it says Failed to start apparmor initialization. When I try to start it manually it fails again and tells me to run systemctl status apparmor.service. When I run that this is the result:


● apparmor.service - AppArmor initialization

I also tried uninstalling apparmor and reinstalling, and running apt clean. Didn't change anything.

How can I fix this? Should I even worry about it?

Hi and welcome to the forums :-)

Start by taking a look here https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1756800

If there are profiles no longer needed or perhaps corrupted it shows those errors.

There are discussions in the thread of what to do.

Hope this helps.

Thank you for replying, sorry I have been busy I haven't been able to mess with this. Nothing on the page seemed to help. I tried replacing those 2 profiles, as well as the ones listed in my error but it didn't change anything. I'm not sure what else to do.

Hi cookie505,

I have not discovered a solution yet

I figured it out

I had to install snapd


sudo apt install snapd

Don't know why this didn't happen automatically but it is what it is
