Due to Fedora Remix is a Remix the dnf copr enable messes up with the distribution name so we must specify it.

Instead of running like this:

sudo dnf copr enable copr_username/copr_projectname

Type this:

(source /etc/os-release && sudo dnf copr enable copr_username/copr_projectname ${ID_LIKE}-${VERSION_ID}-$(uname -m))

For example:

(source /etc/os-release && sudo dnf copr enable wslutilities/wslu ${ID_LIKE}-${VERSION_ID}-$(uname -m))
