I am closing this as it prevents migration and is actually resolved.
The bug was caused by incompatibilities in scotch 7.0 in earlier packages.
These are resolved now and the packages
builds with the current version 7.0.7-1.
Everything builds now, but the following looks like a regression to me:

I think this is due to different Debian package versions of scotch being
used for opm-grid (7.0.10-2) and opm-simulators (7.0.10-7).
The former did not install metis.h in /usr/include/metis while the latter
does.
That seems to be correct according to both the build logs and some local
testing.
While I don't think that there is an big problem with this, we should
probably still recompile opm-grid to have both modules use
the same defines.
The define is uses in a header and source file, but the API should be
unchanged. It will skip some better setting even if scotch is found.
Can someone trigger a binary rebuild of opm-grid or do we need an unchanged
source upload with a version bump?
Emilio, while not strictly required for the scotch transition (the old
scotch packages have been removed from testing) the following will fix
the above issue:
wb nmu 3 opm-grid_2025.10+ds-1 . amd64 arm64 ppc64el riscv64 loong64 . -m
'Rebuild against scotch 7.0.10-7'
wb nmu 1 opm-simulators_2025.10+ds-4 . amd64 arm64 ppc64el riscv64 loong64 . -m
'Rebuild against scotch 7.0.10-7'
wb dw opm-simulators_2025.10+ds-4 . amd64 arm64 ppc64el riscv64 loong64 . -m
'libopm-grid-dev (>= 2025.10+ds-1+b3)'
Scheduled.
