Comment 5 for bug 1979260

Yeah, what @Nobuto says makes total sense.

I couldn't find any file logs.
So I ran the action again to take a look and now it seemed to have worked

juju run-action glance-simplestreams-sync/1 sync-images --wait

Could have just been a connectivity issue during the first time I run the action
