Hello! I’m very new to Ubuntu and LXC and trying to reproduce the container creation from a book!
NAME="Ubuntu"
VERSION="14.04.6 LTS, Trusty Tahr"
lxc-ls --version
1.0.10
But I found this in the logs after
lxc-start -d -n MyContainer --logfile=/var/log/lxc/lxc.log
lxc-start 1595188211.388 ERROR lxc_cgmanager - cgmanager.c:lxc_cgmanager_create:301 - call to cgmanager_create_sync failed: invalid request
lxc-start 1595188211.388 ERROR lxc_cgmanager - cgmanager.c:lxc_cgmanager_create:303 - Failed to create net_prio:lxc/MyContainer

lxc-start 1595188216.396 ERROR lxc_start_ui - lxc_start.c:main:341 - The container failed to start.
lxc-start 1595188216.396 ERROR lxc_start_ui - lxc_start.c:main:343 - To get more details, run the container in foreground mode.
lxc-start 1595188216.396 ERROR lxc_start_ui - lxc_start.c:main:345 - Additional information can be obtained by setting the --logfile and --logpriority options.
Could you help me to find the mistake please?
UPD
debug is
