Trying to update yum...couple of issues...

So let me start by saying I'm no Linux pro, I am just knowledgeable enough to be dangerous. I got a VPS running Cent which I tried updating today and got the following. A quick search yielded similar issues but no direct discussions on fixes. Any idea about the best course of action here? Thanks!

 You could try using --skip-broken to work around the problem
** Found 2 pre-existing rpmdb problem(s), 'yum check' output follows:
frontpage-2002-SR1.2.i386 has missing requires of libexpat.so.0
mod_dav_svn-1.6.11-7.el6.x86_64 has missing requires of httpd-mmn = ('0', '20051115', None)
checkyum version 21.1

 

Thanks for the response. I think I followed some tutorial which had me using the custom repo to install ffmpeg. The Dag repo now that you mention it. Is there some way to update everything except those items throwing the errors? I tried --skip-broken to no avail.

NM renamed dag and one other repo file to disable it and now the update is taking place. Thanks for your original fast response. I probably wouldn't have realized to look at the repos. Please feel free to lock/delete the thread.
