Thanks, I'll have a look at the logs for postgis-source.

In general, no. The PostgreSQL team is more appropriate for PostgreSQL
extensions in general.

In the case of PostGIS, pgRouting and pg_comparator, these are
appropriate in Debian GIS, especially the former two which are OSGeo
projects. PostGIS is an essential project in the GIS ecosystem, and all
its GIS related dependencies (gdal, geos, proj & sfcgal) are all
maintained by the the Debian GIS team too. This was my motivation to
move postgis to the Debian GIS team three years ago. The GIS team is the
appropriate place to integrate GIS packages in Debian.

This is indeed something that needs to be fixed, as postgis-binaries
built successfully on these distributions before.

Since Jenkins now uses SSO I can at least access the web interface which
was not possible before. I don't really need to upload to PGDG.

As said, I'll have a look at the failures on the older distributions,
those should be fixed.

Kind Regards,
