debian lxc create error

Question

I recently freshly installed Debian 8, and i want to create a linux contener based on wheezy. But when i launch the command:

sudo lxc-create -n omvctr -t debian -- -r wheezy -a amd64

I obtain this trace :

What is the problem ?

Answer 1

Looks like you run into (sort of) a bug in Debian LXC package, the message:

update-rc.d: error: cannot find a LSB script for hwclockfirst.sh

is probably caused by this line:

chroot $rootfs /usr/sbin/update-rc.d -f hwclockfirst.sh disable

which is trying to disable autostart of several services inside new container, but hwclockfirst.sh service doesn't exist. It would be cleaner if the script would check if service exists and then tried to disable it.

TL;DR: no need to worry :)
