If you have ubuntugis-unstable installed too, it’s quite possible that your GEOS is coming from ubuntugis unstable
and your postgis is coming from apt.postgresql.org. Even worse as I recall, I think ubuntugis relegates compiling of postgis upstream (main repo), so you might still end up with a PostGIS compiled with a lower version. apt.postgresql.org builds against whatever the base repo is of Ubuntu/Debian etc. Last I checked, all stable releases (at least for Ubuntu) I could get put you at GEOS 3.10. So I suspect your Mint postgis was at best compiled with GEOS 3.10. Unfortunately the GEOS is checked at compile time for enabling features, not runtime, but our full version exposes the runtime that is being used, which for most cases is useful, except for the case where new features are disabled. Sandro and Paul, is there any way we can expose the compiled version of GEOS and Proj? This isn’t the first time someone has been confused by this issue and it’s been even worse with Proj (around those times when the proj.db changed) I think I asked before but I forget what you two answered.

According to the postgis_full_version both installations should support geos 3.11, but I do get the error anyway. I'm using pgadmin4-desktop (installed via apt https://www.pgadmin.org/download/pgadmin-4-apt/) to execute the queries. postgis_full_version: * windows: POSTGIS="3.3.2 3.3.2" [EXTENSION] PGSQL="140" GEOS="3.11.1-CAPI-1.17.1" PROJ="7.2.1" LIBXML="2.9.9" LIBJSON="0.12" LIBPROTOBUF="1.2.1" WAGYU="0.5.0 (Internal)" * linux mint: POSTGIS="3.3.2 4975da8" [EXTENSION] PGSQL="150" GEOS="3.11.1-CAPI-1.17.1" PROJ="8.2.1" LIBXML="2.9.13" LIBJSON="0.15" LIBPROTOBUF="1.3.3" WAGYU="0.5.0 (Internal)" The linux mint is a fresh installation, I installed postgresql and postgis via PostgreSQL Apt Repository (https://www.postgresql.org/download/linux/ubuntu/), using the command: * sudo apt install postgresql-15 postgis postgresql-15-postgis-3 Another ppa I have in use is ubuntugis-unstable, it also includes postgis - could this be a reason for the problem? Help would be greatly appreciated.
