Zesty apt sources fail; Zesty is EOL

[conorsch]

Bug

Description

Our build logic uses apt repos from Ubuntu Zesty for modern versions of gettext—specifically, for fuzzy matching support. Zesty reached end-of-life (EOL) on 2018-01-13. The zesty dist is now gone from the Canonical repos: http://archive.ubuntu.com/ubuntu/dists/

Steps to Reproduce

1. Run vagrant up development.

Expected Behavior

Observe development VM provisioned successfully.

Actual Behavior

Development VM fails during Ansible run due to the zesty apt requirement:

TASK [app-test : Add gettext zesty apt repository] *****************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: , E:Some index files failed to download. They have been ignored, or old ones used instead.

Comments

We should swap the zesty apt repo requirement for a different modern version of Ubuntu. Consult the EOL dates: https://wiki.ubuntu.com/Releases Is Xenial appropriate? That'd be excellent if so—since we're evaluating a transition to Xenial anyway (#1530)—but I assume @dachary's already investigated that and decided the Xenial version was not sufficient, thus the Zesty requirement in the first place.
