THIS IS NOT YET AN ISSUE since the repositories in question don't yet contain
anything AFAICT, and I believe that users of the 15.2 "beta" release ought to
understand that and not panic.

However, the 15.2 "final" release date approaches (Gold Master foreseen for 25
June followed by public release on the next Thursday i.e. 2 July) and among its
users there are some beginners who might panic if their update repositories are
listed as "outdated" or "invalid". Please correct the problem before then.

Here is what I see when I run "zypper lu -t package -t patch" with all 15.2
repositories enabled:
- Update-OSS
- Update-NonOSS
- Debug-Update-OSS
- Debug-Update-NonOSS
Warning: Repository <name> appears to be outdated. Consider using a different
mirror or server.

- Update-Test:
Repository 'SUSE:Leap-15.2-Update-Test' is invalid.
[uT|http://download.opensuse.org/update/leap/15.2-test/] Repository type can't
be determined.
Please check if the URIs defined for this repository are pointing to a valid
repository.
Skipping repository 'SUSE:Leap-15.2-Update-Test' because of the above error.
Some of the repositories have not been refreshed because of an error.

(No error or warning for the other repositories)

with exit status 106 if update-Test is enabled, otherwise 0 even if all four
others are enabled.

FWIW, here is the output of "zypper lr -up"; then I'm going to temporarily
disable the Update-Test repository, which BTW I have found to exist online, but
as a totally empty directory.
