I think it's a conflict between connman and network-manager. For this I followed Debian but as I said, nothing is fixed for now.

Need to get 0 B/376 kB of archives. After this operation, 9022 kB disk space will be freed. Do you want to continue? [Y/n] I blindly did this earlier and it broke all network functionality. Also, removing ubuntu-minimal really isn't good. I looked in the dependencies for that package and cmst was in fact listed. Just out of curiosity, what was your reasoning for doing that? What does cmst do that warrants removing those packages? Just curious, before we start getting an ISO and such. I'm just making sure everything doesn't break. :) -- Simon Quigley <a href="mailto:tsimonq2@ubuntu.com">tsimonq2@ubuntu.com</a> tsimonq2 on Freenode </blockquote></div>
