`juju refresh indico --switch indico --channel=stable` is the only iteration of the juju refresh command I'd expect to work. Though the error messages with the other attempts need to be reworded for clarity

I've also tried with the command suggested above (for another charm) and that doesn't work:

```
mthaddon@finistere:~$ juju refresh nginx-ingress-integrator --switch nginx-ingress-integrator --channel=latest/edge
charm "nginx-ingress-integrator": already up-to-date

I would expect it would switch me to the edge channel, which has revision 42.

Well it turns out charmhub may be returning the wrong revision. Looking at https://charmhub.io/nginx-ingress-integrator?channel=edge currently I see revision 42, published today, but when I do a `juju deploy` locally of the charm in the edge channel I get revision 40.

I believe the issue is that the charm might not be updated across all series (bases) for the edge channel:

Could we confirm if this is still not working?

New behavior and output:

$ juju deploy ubuntu
$ juju refresh ubuntu --channel edge
charm "ubuntu": already up-to-date. Note: all future refreshes will now use channel "edge"
