The software properties screen freezes when I update the software cache

[Uygar Demir Koç]

I am currently using Ubuntu 20.04, but I had the same problem in 19.10. When I make changes to the software resources, when closing the program, "Update the software cache?" I come across the question. If I say yes, it updates the cache but the window freezes. It cannot be closed in any way.

Thank you for your bug report, could you add your 'journalctl -b 0' log after getting the issue?

I saved the output of 'journalctl -b 0' to a file. It's in the attachments.
