<![CDATA[Apparmor weird bug: ubports doesn't reboot unless the apparmor cache is deleted.]]>Hello.

I'm trying to port Ubports to Xiaomi Redmi Note 9/Pro/S and I'm encountering a strange bug with AppArmor:

The first boot works fine but after I try to reboot the phone it gets stuck at the Redmi logo and the only way to make it boot is by deleting the apparmor folder from /var/cache/.

I've spend 2 days going back and forward and I still haven't found a fix or a reason why this happens.

Did anyone encountered this problem while porting ubports to their device?

Halium branch: halium10
Kernel sources: https://github.com/nitanmarcel/kernel_xiaomi_sm6250
Ubports gitlab repo: https://gitlab.com/nitanmarcel/miatool-halium

Thanks!

I still have no idea why the vendor messed up apparmor but anyway, if someone happens to have the same problem he could try using different vendor images.

Edit: False alarm. it looks like it didn't boot this time even after deleting that file

Edit: Again. It booted but after I deleted the folder, booted and then started all over but just by deleting the file
