Comment # 7 on bug 1107253 from Imobach Gonzalez Sosa

I've open a PR that fixes the issue:

https://github.com/SUSE/yast2-rmt/pull/35/files

The problem was that we changed our System library and we did not know about
this module. You can find further details in this document:
https://github.com/yast/yast-yast2/blob/master/library/system/doc/system_services.md

Regards,
Imo
