pveversion is at the bottom to save time for people looking only for the fix.
Generally I do not use apparmor on my containers and I find them suitably secure as they are.
But recently I experienced a situation where I had to get apparmor working, if not just temporarily.
During the installation of i2p on Debian, one of its dependencies is a working apparmor installation requirement.
You will receive this error at the end of following the instructions for installation of i2p from their website.
And then if you check the apparmor status, you will see this error:
*NOTE* This is the same error regardless if it is a privileged or unprivileged container.
The fix for unprivileged containers:
Stop your container, add this entry to the bottom of your lxc machine config and start it again.
That's it.
The fix for privileged containers:
Do the same fix from the unprivileged container as well as add these lines as well to lxc machine config.
Please note there is some nuance to these settings and may affect security. This is the configuration that works for me in the time I have availiable to research.
On both privileged/unprivileged container configs I have enabled all other options and do not know if they are needed for this to succeed.
After applying the fixes and rebooting, then reinstall i2p
apt install i2p
Should complete without errors.
Bonus points:
After installing i2p successfully, if you read the file
It mentions to run
in which you can disable the dependency for apparmor, and once reconfiguring it, you can disable apparmor if you do not need it.
Unfortunately, if you try and run this command before i2p installation is marked as properly installed, it will not work.
There may be a way but I do not know this knowledge.
I consider apparmor being a forced requirement on install a bug of i2p. It should install properly then bring up the configuration to enable/disable apparmor requirements. Oh well.
