Comment 3 for bug 1815231

Actually, I've discovered that the test host that I was using had a host network/connectivity issue. On a clean run in our lab, I'm not able to reproduce the issue.

If there is a cache/proxy/mirror mechanism in place on your network, please ensure it is up-to-date and healthy.

If the issue persists, please provide the following additional detail:

Juju version
Host version details
Image source details

Related to, but not directly causing this bug, I've raised a gerrit review to improve visibility and earlier and more clear failure mode when the early apt operations fail (for any reason).
