yum groups

[Pittigher, Raymond - ES]

After a fedup to version 19 I no longer can add or remove groups. If I try to remove a desktop or even do a group list I get this message:

yum group list
Loaded plugins: langpacks, refresh-packagekit
There is no installed groups file.
Available environment groups:
   GNOME Desktop
   KDE Plasma Workspaces
   Xfce Desktop
   LXDE Desktop
   Cinnamon Desktop
   MATE Desktop
.......

I do have the Cinnamon Desktop installed from 18 and want to remove it which shows:

yum group remove "Cinnamon Desktop"
Loaded plugins: langpacks, refresh-packagekit
There is no installed groups file.
No environment named Cinnamon Desktop exists
No group named Cinnamon Desktop exists
No packages to remove from groups


I have google'd around a little but did not find anything that helped.
