Hello,
Trying to upgrade to fedora 21. I did:
mount /dev/sr0 /mnt/cdrom
fedup --device /mnt/cdrom --product=nonproduct
then
'System Upgrade sda (fedup)
But it failed and reboot:
I just had time to see something like
Failed to mount ....
Is it because it did not mount /dev/sr0 ?
Maybe, who knows.
According to fedup's man page, --device takes either a device or a
mountpoint. Try using --device /dev/sr0, without mounting the cdrom.
