apt trying to install a package version not in the repo

[evilbunny]

So a combination of trying the commands
https://wiki.debian.org/Mobian/Tweaks#Au...pp_scaling (cause I wanted postmarketostweaks)
"apt update"
"apt upgrade"
has resulted in apt trying to install from "http://deb.debian.org/debian/pool/main/d/dbus/libdbus-1-dev_1.14.6-1_arm64.deb" However that 404s and looking up one directory in the url, I'm wondering where it got that version number, as versions 1.14.10-* are all older than my mobian install (I installed it this month!).
I have checked my sources files match the ones listed at https://blog.mobian.org/posts/2023/06/10/bookworm/

Given I now can't get apt install or remove cause of this I'd like to know how to fix this in either direction? Either remove what wants to install libdbus or get apt to fetch a version actually in the repo.
(yes I've already tried google I might not know the right search terms, so I'll happy take advice there too!).

Did you look in this directory for a near version?
