1. Only certain repos have groups.
2. yum downloads the groups file based on the contents of repomd.xml

# yum grouplist is usually enough, unless you are within /etc/yum.conf's 
   metadata_expire= period (tells yum not to go check for the live repo 
data again, if you have just got it)

has a grouplist.

# yum --enablerepo=core grouplist

if that doesn't get it, try a clean and repeat the above.
# yum clean metadata

If this doesn't work, then permissions could be a problem.
