I’ve been playing with Fedora for a few weeks now, and, one of the things I’ve noticed is that using the software updates installer (GUI) is nearly useless. It is slow, and crashes nearly every time!
After doing a bit of ‘Googling’, I found that there are a few recommendations for yum mirrors. Here are two that I found, and that work.
To add these to your yum list of mirrors, edit the yum.conf file, located in /etc/yum.conf (Fedora 12)
Add these two lines to the bottom of the yum.conf file:
Save the file and exit. From the command line, (logged in as root or with sudo privileges) do this:
$ yum check-update
$ yum update
The list of updates should populate, and the updates should start downloading a bit faster. It worked for me.
