This is going to sound rather strange. But is it possible when you have not set OpenSUSE to update at, as I prefer to manually update my computer, for it to update by itself.
Last night I fell asleep with my computer on, woke up this morning and Plasma is crashing, but the weird thing is, the plasma tool thing in the top right hand corner has new options on it that were not there when I last updated, and were not there when I went to bed last night. One of them being “Add Activity”. It’s just like somehow my computer has updated without it being set to automatically update. I noticed there are a number of downgrades in the repository today, but still not sure how this could happen?
