UPD: a workaround is to pass update repo thru -u option:
rdopkg update -u
git+ssh://<username>@code.engineering.redhat.com/rdo-update.git
Sorry about that, rdopkg tool was updated to point to the new public
gerrit which is not ready yet, your workaround is correct but of
course only Red Hat folks can use it for now.
Moving rdoupdate.git to the public gerrit is a priority, Steve is in
the process of reconfiguring CI jobs.
Cheers,
