AppArmor docker profile corrpuption problem

appArmorDockerProfileCorrpution.md

Due to a file corruption or some reason I started getting below error

AppArmor enabled on system but the docker-default profile could not be loaded: strconv.Atoi: parsing "found": invalid syntax

I followed below steps to fix this problem. Please take backup of AppArmor profiles if you created any before running below commands

sudo rm -rf /etc/apparmor*
sudo apt remove --assume-yes --purge apparmor
sudo apt install apparmor

The thing is that the files in /etc/apparmor.d come from more than just the apparmor package. There are profile files from packages like isc-dhcp-client, ntp, rsyslog, snapd, tcpdump, and liblxc-common. So what you're doing is wiping out all the MAC security for dhcp-client, ntp, rsyslog, snapd, etc. and weakening O/S security as a result.

I think https://docs.docker.com/engine/security/apparmor/ provides some indication of the issues with using apparmor and docker.
