--- Comment #10 from Rosanne DiMesio dimesio@earthlink.net --- It's easier to just download the packages and install them from your hard drive. The forum topic mentioned in comment 2 has direct links to each of the repositories.
If you want to add the OBS repository, you have to download and add the OBS Release.key first. The specific command to add the repository will depend on which one you are trying to add.
If you need further help, ask on the forum.
