YUM failures

[Kevin Kempter]

I'm getting this:

# yum --disablerepo=livna update
poptop-stable             100% |=========================| 1.9 kB    00:00
http://poptop.sourceforge.net/yum/stable/fc7/i386/repodata/primary.sqlite.bz...: 
[Errno 12] Timeout: <urlopen error timed out>
Trying other mirror.
Error: failure: repodata/primary.sqlite.bz2 from poptop-stable: [Errno 256] No 
more mirrors to try.

Any thoughts ?

Thanks in advance
