Comment 1 for bug 1790151

There are a few things that might be at play here.

First, can you verify that there is no value set for "container-image-metadata-url"?

I had a quick scan of the streams on cloud-images.ubuntu.com and there does seem to be both released and daily builds for that architecture. The default is to fall back from released to daily if not found.

Second, note that if Juju has deployed a container, the image will be saved on the machine with a juju-specific alias. This alias does not factor the stream, so if you have an image, change the stream, and deploy a container on the same host, then the alias hit will give the same image as before.

Can you verify whether this is the case?
