Package: libmeep33
Version: 1.29.0-1
Severity: serious
User: [email protected]
Usertags: fileconflict
Control: affects -1 + libmeep30
Both libmeep30/bookworm and libmeep33/trixie contain overlapping files
matching /usr/share/meep/*.scm. Therefore, unpacking libmeep33/trixie on
a bookworm system containing libmeep30 fails.
mmdebstrap --verbose --variant=apt '' /dev/null 'deb
http://deb.debian.org/debian bookworm main' --include=libmeep30
--chrooted-customize-hook='sed -i -e s/bookworm/trixie/ /etc/apt/sources.list
&& apt-get update && apt-get download libmeep33 && dpkg --unpack

This demonstrates the error.

Errors were encountered while processing:

The error does not presently show up in simple upgrade scenarios,
because other relations tend to force deinstallation of libmeep30.
Still, libmeep33 should declare Breaks + Replaces here.
I note that this also is a violation of Debian policy 8.2. Please fix
that as well.
