[mythtv-users] how to undo mythbuntu update

[David L]

I submitted a bug report for a mythfrontend crash:

http://svn.mythtv.org/trac/ticket/7797

I got a reply that said they  needed more info (not sure why,
I get about this amount of information from my company's
crash reports and find line numbers with addr2line even though
the testers don't have debugging symbols).  Anyway,
I tried this procedure:

http://www.mythtv.org/wiki/Debugging#Debugging_with_Ubuntu_packages

Now my frontend doesn't work anymore.  It says please wait
forever and I get this output:

How do I revert to my previous configuration?  I tried the process for
installing
debugging info without the recommended update, but I got errors installing those
packages.

Thanks,
