Yea, I managed to get updatesd turned off and at least now the add/remove software and yum extender will load, but now they wont conntect to anything. Yum in F8 has some real issues that need to be addressed. There are a lot of people having the exact same issue I am having, but no fix. I guess I'm going to have to try another Distro as an OS that cant be updated or new applications installed is pretty much worthless.
Just another example why people get so frustrated with Linux, and Microsoft continues to dominate.....
