Hi.
I often activate my wifi printer from the printer dialog that I start graphically from Yast, but for some reason the printer dialog doesn’t pop up anymore? I have done some minor attempts to update to latest versions and restart, but without any success.
How do I debug what’s going on? Where do I find the logs?
Can I open the printer dialog from command line, to hopefully get some more message about why it is not starting?

Examine /var/log/YaST2/y2log for relevant errors. You could open a terminal and run
sudo tail -f /var/log/YaST2/y2log
then try launching the YaST > Hardware > Printer utility. Observe/capture the output, and post the output here if further assistance required.

Best to tell us exactly what steps you did here. How did you update specifically?
Are your repos consistent for TW?

Great! This points out that I have lost QT or parts of it.
Here are my repos:

But how do I get QT back in place?
# zypper if qt

Reading installed packages...
package 'qt' not found.

This actually sounds like an issue where the libyu qt8 packages are missing, try this;
sudo zypper in libyui-qt8 libyui-qt-pkg8
It looks like it is not in any of the repos?
# zypper in liblibyui-qt8 libyui-qt8-pkg8Loading repository data...
Reading installed packages...
Package 'libyui-qt8-pkg8' not found.
'liblibyui-qt8' not found in package names. Trying capabilities.
No provider of 'liblibyui-qt8' found.
Resolving package dependencies...
Nothing to do.
No such packages 
Copy the command as it was given to you. It should be ‘libyui-qt8’ and ‘libyui-qt-pkg8’.
This was actually my mistake, fire was so fast he must’ve seen my pre-edit one. OP; please check my revised post a minute after I posted it 
I should just copy paste and not type them by hand…
Thank you very much! Just wanted to confirm that it works now!
