[Debian-med-packaging] Bug#1109178: emmax: fails to dist-upgrade from bookworm (related to libatlas3-base removal)

[Lucas Nussbaum]

Package: emmax
Version: 0~beta.20100307-5
Severity: serious

Hi,

The following fails:
- In bookworm, install emmax
- dist-upgrade to trixie
I would expect emmax to be upgraded, but it is not.

MWE:
PKG=emmax; 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 && apt dist-upgrade -y -o Debug::pkgProblemResolver=true" bookworm /dev/null
