Description Chris Lumens 2011-06-01 15:44:20 EDT
backends/yum/yumBackend.py assumes that .discinfo is four lines long and contains a disc number.  The disc number is gone in F15, so as a result the backend will throw out valid media because it doesn't understand the new format.  See:  http://git.fedorahosted.org/git/?p=lorax.git;a=blob;f=src/pylorax/discinfo.py;h=24f435f4d8a8accf4804a21381c5e35b484a651c;hb=HEAD

I'd think the following patch would fix it up, though I have not tested it to be sure.

Comment 1 Máirín Duffy 2011-06-09 16:36:56 EDT
Just wanted to note the impact on users here is that users with no or poor internet connections won't be able to install additional software post-install. (we are looking at removing individual package selection from the installer in the future which would greatly exacerbate the problem)

I've made a small fix to your patch, and pushed it to git master. Thanks.
