We've confirmed our update is working as expected and previously errored builds will be able to `sudo apt-get install ...` if rerun. If you still see issues, please email support@travis-ci.com

Monitoring
We've deployed an update which has restored things so that `sudo apt-get update` is run at the beginning of builds, which will result in successful `sudo apt-get install ...` commands. We're following with up with all users who reported issues.

Identified
Yesterday we made a change to no longer try to install a libc update in our sudo enabled images at runtime, as it's now pre-installed, but we've determined that removing it has removed a `sudo apt-get update` that was running at the beginning of every build and the removal of this is causing issues for many users. We are rolling back this change now.
