This might be a related issue…
Difference is, that lxd/lxc was already installed and working fine prior to a kernel upgrade.
After upgrade from kernel 5.15.102-1 to kernel 6.1.19-1 I get a similar error message:
$ lxc list
cat: /proc/self/attr/current: Invalid argument
aa-exec: ERROR: AppArmor interface not available
I am also running Manjaro
$ uname -srvm
