"Unresolvable: nothing provides obs-service-tar, nothing provides obs-service-recompress" Since some time, Open Build Service's recommended 'checkout sources from git and make a tarball' service stores the sources as .obscpio files. Its documentations strongly encourages to use the "buildtime" option to convert the obscpio file to tar only when the build process is running and not permanently store the tarball on the server. That, however, requires above mentioned services "obs-service-tar" and "obs-service-recompress" to be packaged by the distributions ("obs-service-set_version" is already packaged for Fedora).
I'm working on it...
