Hi all, Okay, as I was writing this email to the list, I figured out what was going on. I thought I might as well send it with the solution in case someone else runs into this problem. The Problem: I just finished installing FC3 i386 on a machine at work, and I was trying to setup the Fedora Extras repo. However, yum doesn't seem to like the baseurl. Whenever I run "yum update" I get the following: Setting up Update Process Setting up Repos Cannot find a valid baseurl for repo: extras Okay, well recent attempts to navigate to the repo with Firefox haven't gone too well, Firefox locked up. I was able however to get telnet to dump the index page for http://download.fedora.redhat.com/pub/fedora/linux/extras/3/i386/ I thought, well I'll just disable extras right now until it clears up, but adding "enabled=0" doesn't change the behavior. I still get the above error. The only thing that works is moving the fedora-extras.repo to a sub-folder in /etc/yum.repos.d/ (as would moving it anywhere else I assume). I even have a .repo for the debug stuff, and yum works just fine with it disabled. I just checked, and extras works just fine for a machine at home. Without the fedora-extras.repo file, yum works fine. The Solution: It turns out that the fedora-extras.repo file had carriage returns ('\r' 0x0D) in it instead of the normal UNIX new lines ('\n' 0x0A). I'm not sure how that happened. I copied and pasted the stuff from the EXTRAS file on the main repo site into nedit. I also had to add the returns, since it all pasted on one line. Anyway, I was using nedit to view/edit the files, which did not reveal the error. Attempting to use "cat" or "vi" to display the file exposed the returns as being only carriage returns and not the expected new lines. A hex editor also shows what was going on. I'm still not sure why Firefox didn't like trying to list the repo (perhaps it was just having trouble with such a large page and I was impatient), but simply re-creating the file (being sure nedit used new lines this time) has solved the problem.
