Hi,

The following fails:
- In bookworm, install liblldb-dev
- dist-upgrade to trixie
I would expect liblldb-dev to be upgraded, but it is not. It remains at the bookworm version.
'apt install'ing manually in trixie works fine.

There might be some missing Replaces/Provides somewhere to hint apt at upgrading the package.

MWE:
PKG=liblldb-dev; mmdebstrap --chrooted-customize-hook="set -x ; apt -y install $PKG  && sed -e s/bookworm/trixie/ -i /etc/apt/sources.list && apt update && apt dist-upgrade -y -o Debug::pkgProblemResolver=true && apt -y install $PKG" bookworm /dev/null

Relevant part:
