Hi, I've tried to reproduce this issue by upgrading a Mobian VM from bookworm to trixie. Starting from a bookworm system with both plasma-mobile and kde-config-mobile-networking, the upgrade to trixie is going through without errors related to any conflict between these two packages. I'll try to share upgrade's report via a separate mail, I guess having an attachment AND a link in a single mail triggers BTS' spam filter...
OTOH, it's my fault that I specified kde-config-mobile-networking in plasma-mobile's Breaks, but not in the Replaces. This is going to be fixed as soon as next upgrade for plasma-mobile [1] gets reviewed and pushed to the archive.
