Thanks, libgdal (3.2.2-1) will need to be unblocked as well, it goes
libgdal-grass ?
hand in hand with gdal (3.2.2+dfsg-1). libgdal needs the same upstream
version of gdal to build successfully.
Please go ahead with an upload adding a gdal3-data binary package.
That's much more invasive as suggested in #986975 as it will need to
pass NEW in addition to an unblock.
And it does not really help, since it just uncovers that there are more
dependencies on not co-installable libraries: libogdi3.2/libogdi4.1 due
to plugins in unversioned paths. Theoretically fixable as well by moving
the plugins to a versioned path. Not sure what would show up next.
#986975 just adds Breaks: libgdal20 to libgdal28 for smoother upgrades
from buster, that seems like a reasonable change.
See attached patch. Especially for its very verbose changelog entry ;-)
We may need to add this Breaks in some more packages since in rare cases
old libgdal20 scores higher than libgdal28. But most cases are already
covered with libgdal28.
