Nope had to stop on episode 16. Just got in.
Ok I am doing a fresh install on ubuntu 12.04.1. with current core 3.0.8.
My first attempt was just to setup the networking and then install samba and let it bring in all the modules.
Banged out and it looks like there are apparmour probs like previously suggested.
I am just having a look through the logs.
[actually apparmor just caught my eye but that is just a profile update]
dns updates don't seem to be liked.
Might be that DNS hasn't even been enabled yet.
