Hi all, Using build x86_64-20140630 (and previous [Grrr, I've just noticed x86_64-20140702, I'll try that once I've got it down]), I can do a "yum -v grouplist" and get what looks like the correct output, but when I try installing one of the groups, the following happens - %%%%%%%%%%%%%%%%%%%%% [root at maintsas ~]# yum groupinstall scientific Loaded plugins: fastestmirror There is no installed groups file. Maybe run: yum groups mark convert (see man yum) base | 3.6 kB 00:00:00 epel | 3.7 kB 00:00:00 Loading mirror speeds from cached hostfile Warning: Group scientific does not have any packages to install. Maybe run: yum groups mark install (see man yum) No packages in any requested group available to install or update %%%%%%%%%%%%%%%%%%%%% I'm fairly sure this shouldn't be happening :) -- Cheers!
