Public bug reported:
Hello.
When testing with the bionic-proposed repository, we found that the
4.15.0-149-generic break the lxc-attach command with the following
error:
lxc-attach: bidule: lsm/lsm.c: lsm_process_label_set_at: 174 Operation
not permitted - Failed to set AppArmor label "lxc-container-default-
cgns"
We don't have this issue with the current 4.15.0-147.
There is no issue using the --elevated-privileges option of lxc-attach.
I join the debug log of “lxc-attach -n bidule -l debug”.
