Lab3.2 lxc - permission denied - apparmor error?

Hello,

I seem to be unable to start a new unpriviliged container with lxc

$ lxc-start -n unpriv-cont-user -F
lxc-start: unpriv-cont-user: ../src/lxc/lsm/apparmor.c: make_apparmor_namespace: 869 Permission denied - Error creating AppArmor namespace: /sys/kernel/security/apparmor/policy/namespaces/lxc-unpriv-cont-user_<-home-cherif-.local-share-lxc>

lxc-start: unpriv-cont-user: ../src/lxc/tools/lxc_start.c: main: 311 Additional information can be obtained by setting the --logfile and --logpriority options
