I changed my mother board and had to convert a legacy boot to efi and messed it up so I attempted to install Leap:15.4 fresh. For this I used a downloaded image installed on a usb stick first via dd_rescue direct and the last Tumbleweed stick via live-fat-stick. All of these attempts have had "wrong digest" errors which I ignored and eventually crashed. I thought this was due to my new mother board maybe so I decided to use a spare known to be good hard drive to install via my working Tumbleweed laptop (it already uses efi) using a usb adapter. Still "wrong digest" errors and they appear to be exactly the same files. Help!!! I have important work to finish and will be bankrupt if I don't The one thing related to this pc is that I burned the usb stick on this pc (new motherboard and intermittent crashes) but the micro sd card in reader that I used on my first attempt to install with was burned on the laptop. The packages that fail appear to be the same ones every time. I found a similar problem on the openSUSE forum but it apparently just went away for an unknown reason. PC = generation 4 msi H81I motherboard, 8 gig ram and i5 cpu with new hard disk (my old one started giving smart errors so I replaced it with a new one.) Laptop 6th generation HP Pavillion with i3 6006u cpu and 4 gig ram Please can somebody shed some light on my dilemma.
