keystone charm upgrade generating error

Hi, i have a openstack charmed deployment. I am trying to upgrade the keystone charm. it is set to ussuri/candidate and it is in rev 583. I did:

juju refresh switch ch:keystone --channel ussuri/stable keystone

it generates the following error :

Added charm-hub charm “keystone”, revision 652 in channel ussuri/stable, to the model ERROR charm repository for source “ch” not supported (not supported)

and the charm remains as ussuri/candidate rev 583

any help on how to resolve this will be great. And apparently i am facing this error on other charms from openstack.

Regards, Rony

Hi, solved this by running “juju refresh keystone --channel ussuri/stable”
