"sudo dnf copr enable seeitcoming/rcm" errors out

I am trying out Korora 23 in a VM, and I receive the following output from "sudo dnf copr enable seeitcoming/rcm"

I'm not entirely sure who made this package, so I don't know who to ping on this one. Do you know?

Looking at https://copr.fedorainfracloud.org/coprs/seeitcoming/ and the committers for this repo, I can see seeitcoming has the same profile picture as @supervacuo

Hi, yes, it was me!

This looks like a problem with Korora; I hit their website to find out how it was even using dnf (distro was gentoo-based last time I looked...) and their latest blog post is "When Adding a COPR repo to Korora Fails":

Unfortunately the command provided on the COPR site does not work on Fedora remixes such as Korora. The command attempts to determine the version and arch you are running but doesn't recognise a remix

$ sudo dnf copr enable reponame fedora-23-x86_64

[supervacuo]

fix it, for glittering imaginary internet point prizes:

• edit rcm's README to document this workaround (1 point)
• verify if it's actually a problem with dnf (4 points)
• make sure a bug report is filed wherever it belongs (10 points)
• patch dnf to handle Fedora Remixes correctly (50 points)
• wait for me to do one of the above (0 points ☺)

[BKStephens]

Thanks for finding that! I just tried the workaround, and it works:

sudo dnf copr enable seeitcoming/rcm fedora-23-x86_64

@mike-burns Would you accept a PR to add Korora instructions to the Installation section of the README?

[mike-burns]

I'd love to PR to add Korora instructions to the README.
