Folks,
Currently apt.postgresql.org ships a postgresql-9.4-postgis-2.1 which
depends on a libgdal1 which you also ship. However, this libgdal1 will
not install on Ubuntu Trusty because it is incompatible with the
supporting geo libraries it needs.
Is there a reason why the pgdg postgis doesn't just depend on the
libgdal1h which ships with Ubuntu? That would fix the issue neatly. As
it is, it's not possible to install PostGIS+9.4 using pgdg packages on
Ubuntu.
Is this something which is different on Debian vs. Ubuntu, and that's
the reason for the breakage?
