Attempting to unpack libocsigenserver-ocaml/5.0.1-1+b12 from Debian bookworm
on a minimal Debian bullseye with libocsigenserver-ocaml-dev/2.16.1-1+b3
installed, causes an unpack error from dpkg due to
/usr/lib/ocaml/ocsigenserver/ocsigenserver.cma being contained in both packages.

Please ensure that libocsigenserver-ocaml has sufficient Breaks and Replaces
declarations.
I agree that doctrine says Breaks+Replaces are missing here, and I will
fix that. However, I wonder how one would get the aforementioned error
in practice.
In a minimal bullseye chroot with libocsigenserver-ocaml-dev installed,
after adding bookworm to sources.list:
- "apt upgrade" does not attempt to upgrade libocsigenserver-ocaml
- "apt dist-upgrade" upgrades libocsigenserver-ocaml along with
libocsigenserver-ocaml-dev, with no errors
This is the same outcome with the "fixed" libocsigenserver-ocaml.
Installing with "dpkg -i" does produce the error, but installing the
fixed package with "dpkg -i" also produces an error.
