Instead of full-upgrade, try safe-upgrade. It can usually get you beyond the humps. I also think you are missing a couple of reboots in your command chain. That handles the Aptitude error message. But I think you should be following Debian's published procedure for a dist-upgrade, and not using an ad-hoc procedure someone came up with on the web. The published procedure is available at <https://www.debian.org/releases/trixie/release-notes/upgrading.html>. Jeff
