Unfortunately I can't reproduce this at all, and the logs don't give enough information.

I have asked for the CI tests to be run with --debug rather than just --show-log so we can gather more info.

I see this failure in this[1] run of the model migration aws test. The error in the logs:
  00:13:30 ERROR cmd supercommand.go:458 "" is not a valid tag

I'm not yet able to reproduce this on demand, but I've seen it happen 3 times out of 5 runs this morning.
I'll update when I have further details.

The error itself is coming from
github.com/juju/juju/cmd/juju/controller/listmodels.go:164:
github.com/juju/juju/cmd/juju/common/model.go:70

I am looking into how/why we are getting an "" tag for models.

The issue was hard to track as it was hard to reproduce.
I believe that this PR (against 2.1) is the fix: https://github.com/juju/juju/pull/7011

Let us know if you are still seeing the issue once it lands.
