I have noticed a strange behavior of software manager.
When I want to mark a program to install f.e. iscan my manager is suddenly closed. In my search engine I have written a word: iscan.
But then I have written in my search engine a word: scan and then I have scrolled my mouse down to find iscan. I can mark it and software manager is not closed.
Is this a bug?
Yes, it’s a bug (already reported).
I had the same issue and had to update via konsole and that fixed the issue for me.
Screenshot below shows the updates.
