I've finally solved the issue with : - sudo apt-get purge -y libgeos* libspatialite* - sudo mv /etc/apt/sources.list.d/pgdg* /tmp
geos was pre-installed due to postgis being pre-installed (postgresql-9.1- postgis-2.1, postgresql-9.2-postgis-2.1 and postgresql-9.3-postgis-2.1 ) (I'm not sure if the disabling of pgdg is needed. Was one of my first attempt, but not sufficient by itself) Thanks for you help.
