This software is been keeping my system outdated for the last 2 weeks. And everytime I tried an update the Discovered always said: Dependency resolution failed:problem with the installed librist4-0.2.7-1699.1.pm.29.x86_64
What can I do? Mark this software as: Protected--do not modify So I can update now or wait for a week again?
You can show the full command line and its complete output.
zypper dup
The solution is to use zypper dup to get some solver questions and answer them.
According to another thread, this package got removed from packman and you need to switch the vendor back to openSUSE.
Man I must be able to see the future or something 
No, as said above, you should use zypper dup to keep a Tumbleweed system up to date.
