Description of problem: during upgrade from f16 to 17 this happened to me; system was not bootable any more. grubby fatal error: unable to find a suitable template grubby fatal error: unable to find a suitable template grubby fatal error: unable to find a suitable template (guessing each line for each installed kernel version?) Version-Release number of selected component (if applicable): I guess, version number does not matter, I've seen this on f16, too; it didn't made the system fail.
