This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'

Marking as Invalid because the release is EOL is not correct. Marking as Incomplete. Also, 18.04 is (at the time of writing) still in development, and you should expect some breakage.

Reporter, is this still present on 17.10 or 16.04?
