Hi Jacco.
Looks like raspberrypi4-kernel-devel-5.4.77-v7l.1.el7.armv5tel is not 100% compatible with EL8

Error:
Problem: cannot install the best candidate for the job
- nothing provides /usr/bin/python needed by raspberrypi4-kernel-devel-5.4.77-v7l.1.el7.armv5tel
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Default python is python3 on EL8 🙂
BR,
