ltsp-build-client for mythbuntu 12.04 from Ubuntu 10.04 fails

[Matt]

Attempting to build a 64-bit Mythbuntu 12.04 (Precise) LTSP client, from a 64-bit Ubuntu 10.04.3 (ltsp-server version 5.2.1-0ubuntu9) server, fails due to the "admin" user group not existing.

The command that I am using:
sudo ltsp-build-client --arch amd64 --dist precise --mythbuntu --mythbuntu-user-credentials="mythuser:password"

The messages leading up to the failure:
Adding user `mythuser' ...
Adding new group `mythuser' (1000) ...
Adding new user `mythuser' (1000) with group `mythuser' ...
Creating home directory `/home/mythuser' ...
Copying files from `/etc/skel' ...
usermod: group 'admin' does not exist
error: LTSP client installation ended abnormally

It seems like it is failing because it's attempting to add the mythuser to the admin group, which no longer exists in 12.04. Any workaround for this? Or is it a bug?

The mythbuntu plugin was unmaintained and was removed in 12.04, so even if you had a 12.04 server it wouldn't work. Use a regular fat chroot instead and install mythbuntu in it normally.
