Public bug reported:
I have several user-space LXC 1.0 containers which recently stopped
working (apt-get dist-upgrade 2-3 days ago, maybe?). I've been unable to
start them up, I'm getting:
user@trusty:~$ lxc-start -n sandbox -d
lxc_container: command get_cgroup failed to receive response
Log outut from lxc_start:
lxc-start 1395605212.193 ERROR lxc_apparmor - No such file or directory -
failed to change apparmor profile to lxc-container-default
lxc-start 1395605212.193 ERROR lxc_sync - invalid sequence number 1.
expected 4
lxc-start 1395605212.193 ERROR lxc_start - failed to spawn 'sandbox'
lxc-start 1395605212.193 ERROR lxc_commands - command get_cgroup failed to
receive response
Restarting apparmor seems to indicate a problem with the LXC apparmor
profile:
root@trusty:/sys/fs/cgroup# service apparmor restart
* Reloading AppArmor profiles
Enocoding of mount rule failed
ERROR processing policydb rules for profile lxc-container-default, failed to
