Unable to download list of repositories

I wanted to add the packman repository. From the Yast repositories menu I selected

Community repositories

Next

and received the error popup

Warning

Unable to download list of repositories
or no repositories defined.

Show

zypper lr -d

I made it into habit opening the repo in a browser:

http://ftp.fau.de/packman/suse/openSUSE_Tumbleweed/Essentials/packman-essentials.repo

To add the repo open a root shell and copy and paste the URL into the following command:

erlangen:~ # zypper addrepo --refresh http://ftp.fau.de/packman/suse/openSUSE_Tumbleweed/Essentials/packman-essentials.repo

The advantage of selecting from Community Repositories is that I don’t have to worry about the URL being different from the last time through.

BTW, I submitted a bug report and the problem has been resolved, at least as it affects me.
