Group lists but doesn't exist.

[Frank Murphy]

First release I've used dnf on in a while,
so I may be missing something.


sudo dnf install @development-tools
Warning: Group 'development-tools' does not exist.
Error: Nothing to do.

Try it the other way: 
sudo dnf groupinstall "Development Tools"
Warning: Group 'development-tools' does not exist.
Error: Nothing to do.

So then I do.
$ dnf grouplist
 Development Tools
