I run Proxmox on an ASUS mini PC. I upgraded the RAM and booted the device.
I get the following error message when booting 3 of my LXC containers (running NextCloudPi, Ubuntu running Docker). The rest of my LXC containers are functioning just fine.

load_apparmor_profile: 979 Invalid argument - Failed to mmap old profile from /var/lib/lxc/104/apparmor/lxc-104_<-var-lib-lxc>
apparmor_prepare: 1086 Failed to load generated AppArmor profile
lxc_init: 876 Failed to initialize LSM
__lxc_start: 2027 Failed to initialize container "104"
TASK ERROR: startup for container '104' failed

Could someone help me troubleshoot this issue?
Thank you :)
 
Hi,

Please provide us with the output of the log of the container debug for the 104 CT as attach, by issuing the lxc-start -n 104 -lDEBUG --logfile /tmp/lxc-104.log command. And the output of pveversion -v and the container config as well pct config 104

I'm having the same issue. Getting this error starting my lxc container:

Does anyone have allready a solution? Thanks for any help.

I did a clone of the LXC-Container and now the container working again. But it's realy strange, hope that this is happen not to often...

Do you still have the broken container? Can you check the file it mentions? (/var/lib/lxc/206/apparmor/lxc-206_<-var-lib-lxc>).
I suspect that it might be empty, if that's the you can remove it and see if it starts then. Also, if that's the case, I wonder how it happened and we probably need to handle this in lxc.
 
Hi,

I did a clone and it worked for a while - after 2 days the error came back, on the cloned LXC.
Is there a stable solution - workaround is only short term solution.

what also seem to work is to delete the old file in
/var/lib/lxc/100/apparmor/

Hey,
does it still work for you - here the problem comes back again after rebooting the host.
I need to delete the folder again day by day...

Any ideas how to fix it sustainably ?

Hi,
@olepinguin can you share the output of pveversion -v? AFAIU, the issue should be fixed in pve-lxc >= 5.0.2-2 with this commit.
