Tried to install Trinity Desktop per instructions, and retried after cleaning the Yum cache.

yum install trinity-desktop

Here's the console message:

http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/rpm/el6/trinity-e...: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 416" Trying other mirror. Error: failure: repodata/filelists.sqlite.bz2 from trinity-3.5.13-el6-extras: [Errno 256] No more mirrors to try.

What should I try next?
