Failed to mount cd:/?devices=/dev/disk/by-id/usb-ASUS_SDRW-08D1S-U_4B5A3941335047353530322020202020-0:0 on : Mounting media failed
I have TW installed on ACER nettop without cd at all. Connecting external CD drive does not help. What can be done ?
Hi and welcome to the Forum 
That was your USB install medium, either via YaST -> software repositories or via zypper rr delete or disable the repository.
