Comment # 2 on bug 1203327 from Lubos Kocman

Found the issue (there was some old service entry that I experimented with,
that blocked remaining steps)

(removed openSUSE, trying to add it as "os" a different alias)

lkocman@lkocman:/etc/zypp/repos.d> sudo zypper as /Local/Service os
Setting new service osindeterminate indeterminate
Service 'os' has been successfully added.


(please notice the refreshing service leap ... which is not visible in the lr,
but blocks any further refresh, even if ignored)
