Description of problem:
I am not able to install python2 on centos-stream because of "No available modular metadata for modular package" error.


How reproducible:
Always

Personally I am running Fedora as my host system and reproduce this by using Mock. This is the way we discovered this issue in Copr. The reproducer will probably be even simpler when running Centos Stream system.


Steps to Reproduce:
1. mock -r centos-stream-x86_64 --install python2
