Looking at the failures reported by Koschei after last rubygem-minitest rebase, I'd like to suggest everybody to use the mass-prebuild tool:
https://gitlab.com/fedora/packager-tools/mass-prebuild
This tool allows to rebuild all reverse dependencies in copr, preventing breakages. This would be the minimal config required for minitest:
~~~
$ cat mpb.config archs: x86_64 chroot: fedora-rawhide name: mpb packages: rubygem-minitest: src_type: file src: /home/vondruch/fedora-scm/own/rubygem-minitest/rubygem-minitest-5.19.0-200.fc39.src.rpm verbose: 1 retry: 2
~~~
Which is then executed via simple `mpb` command. Because I'd like to start from scratch, I also like to clean the results of prior run:
~~~
$ mpb --clean --buildid 1
$ rm -rf ~/.mpb/
~~~
This should delete the copr `mpb` repository as well as the mass-prebuild database. But feel free to experiment with the tool. It provides more knobs which allows you to tune the experience to your needs.
HTH
