I am trying to see what slowroll is like and used this guide 
https://en.opensuse.org/openSUSE:Slowroll
 
This is what I get updating Tumbleweed: (most is in red but did not copy)
 
Doesn't look broken from here:

but somewhere I saw written that upgrades can be made to Slowroll from either
Leap or TW, but if done from TW, it should be done from an older TW release, 
ostensibly, one older than the latest Slowroll release. Did you upgrade, or
are you trying to upgrade? If yes, from what releasever?
