The rpmsave file started by openSUSE-repos contains the debug repos. For some reason it does not contain the source code repos. Would I not keep reinstalling them which is not what I want to do?
It is absolutely not hard to understand and achive.
Simply delete the rpmsave files for the debug repos (as you don’t want them). As the source and other important rpmsave files are missing, you already tinkered with your repo list prior installation of the openSUSE-repos-* packages. You need to add the missing repos. Have a look which repos belong to a standard Leap installation: https://en.opensuse.org/Package_repositories
Then follow the instructions from github to restore the base repos.
Add the missing repos according the linked SDB.
And your science, games, graphics, education, geo, and electronics repos stays untouched as they are absolutely not related to the openSUSE-repos-* packages.
