FC2 to FC3 upgrade exits abnormally

[Rick Lim]

I'm trying to upgrade a working FC2 to FC3, having got past the first error
where the harddisk geometry was read wrong by using the parted update, I get
to the point where it starts to begin the install and then I get

warning: package kernel = 2.6.9-1.667 was already added. Replacing with
kernel = 2.6.9-1.667

install exited abnormally.


Any suggestions?
