The latest Tumbleweed image for the Rasberry Pi 1B has two names on the web 
page: openSUSE-Tumbleweed-ARM-JeOS-raspberrypi.armv6l-Current.raw.xz and 
openSUSE-Tumbleweed-ARM-JeOS-raspberrypi.armv6l-2019.05.17-
Snapshot20190607.raw.xz, which is what it should be.
The corresponding sha256 files have the same content. The fourth line in these 
files contains the sha256 checksum followed by the name of the image. However 
this name is:
openSUSE-Tumbleweed-ARM-JeOS-raspberrypi.armv6l-2019.05.17-Build1.43.raw
So one needs to rename the image file before doing the checksum to this name.
Changing the name in this file invalidates the signing of this file.
This name should however also have .xz added at the end.
