How do I see what the conflicting files are? Rightclick on the icon in KDE-Plasme panel does nothting.
Is this really the daily built? In such a case this is more developer-oriented and if these images break, you can check directly with the developers on github. Except for testing, I wouldn’t use a daily version. Perhaps some snap/flatpack/.. show this?
Normally when you leftclick? on the yellow message a window with the conflicts should open. If that does not work and you really need more details, often in the file manager, there is as well a yellow symbol close to the problematic file, and in the logfiles you should get hints as well.

look at your 2nd picture… and you can clearly read “daily build” - and really: you shouldn’t run any daily/nightly builds on productive instances.

And as always: if you meet technical problems don’t forget to post technical details… you know what I am talking about.
I’m not sure what the “daily” means here, but I have the same thing on Arch, with the package from the Arch Repositories:
And no, it’s not updated daily; it’s only updated when a new point release is out. 
well if you say that it seems to be common to Arch … I dunno. I just checked mine and it says 33.0.2. - but I’m running Mint (Ubuntu/Deb)
