Clean install of Wolverine was stopped with a pop up warning as follows:
/mnt/src/redhat/rpms/xpdf-0.92-2.i386.rpm can not be opened due to missing file or bad media etc.
Since I seem to be the first to run into this problem I presume it is bad media...
The bug would be that there is no option to eject the current media or skip the problem package after the warning.
One must either force the cd to eject by sticking a paperclip in the emergency eject hole of the CD player or restart the computer.
There must be a better way.
I just ran into bug report 25724 which seems quite similar ...
Resolving as a dupe of bug #25724. I think ewt's comment on that bug applies here.
