fedora 29, downgrade gcc 8.2 to 7.3

I have fedora 29 and I need downgrade gcc from 8.2 to 7.3 (it is needed for CUDA).

dnf --releasever=27 install gcc-7.3.1-6.fc27

Is not working. I got the error:

Error: Failed to synchronize cache for repo 'fedora-modular'

How to do it?

Try

dnf --releasever=27 --disablerepo=fedora-modular --disablerepo=updates-modular downgrade gcc

This may or may not work, and if it doesn't work I would suggest to install Fedora27 in a virtual machine, as this is a cleaner solution.

The command is working for me, thx.
