Default [Q] CM Build problems

Can someone help me? I can't initiate the repo on my PC. I installed Ubuntu 14.04 LTS and I can't do the repo init.

I got:
Get https://gerrit.googlesource.com/git-repo
fatal: unable to access 'https://gerrit.googlesource.com/git-repo/': Could not resolve host: gerrit.googlesource.com

Or:
fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error [Errno -2] Name or service not known
