I do not agree: HDF5 1.10.2 was uploaded to experimental only. While
this
conflict do exist, there is no unhandled conflict with previous
releases
from testing or unstable.
What is the problem with adding Replaces+Conflicts
also for libhdf5-mpich-101?
I agree that the severity looks less clear if this was
experimental-only,
but it is also pretty easy to do.
Sure, this is an unfortunate oversight from me. But (1) hdf5 1.10.4 is
currently
transitioning and I don't want to delay that anymore, and (2) I expect
that
anybody installing packages from experimental is able to deal with this
kind
of conflict.
In theory (likely not applicable here) it is even possible that some
downstream distribution like Ubuntu shipped the experimental version
in a stable release.
No, ubuntu didn't ship any HDF5 release from experimental. And packages
from
experimental must not be used in any stable release. Quoting the FAQ:
Experimental is used for packages which are still being developed, and
with
a high risk of breaking your system. It's used by developers who'd like
to
study and test bleeding edge software. Users shouldn't be using
packages
from there, because they can be dangerous and harmful even for the most
experienced people.
