Comment 4 for bug 1890437

As @dan.ackerson says this down to a mismatch between the member role created by the keystone charm and the one expected by the dashboard charm. As of 20.05 the member role is called Member rather than member.

To reproduce:
Deploy bionic stein with cs:~openstack-charmers-next/keystone-480
Login to horizon
 Domain: admin_domain
 Username: admin
 Password: $(juju run --unit keystone/0 "leader-get admin_passwd")

Identity -> Projects -> Manage Members

Sign Out

juju upgrade-charm --switch cs:~openstack-charmers-next/keystone keystone

Identity -> Projects -> Manage Members # Silently fails
