<p>Hello,</p>
<p>I'm trying to restore a backup from a windows installation to a
new linux mint 21 installation but it always fails with "error:
Directed line merging requires GEOS-3.11 or higher". 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
<a class="moz-txt-link-freetext" href="https://www.pgadmin.org/download/pgadmin-4-apt/">https://www.pgadmin.org/download/pgadmin-4-apt/</a>) to execute the
queries.<br>
</p>
<p>postgis_full_version:</p>
<ul>
<li>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)"</li>
<li>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)"</li>
</ul>
<p>The linux mint is a fresh installation, I installed postgresql
and postgis via PostgreSQL Apt Repository
(<a class="moz-txt-link-freetext" href="https://www.postgresql.org/download/linux/ubuntu/">https://www.postgresql.org/download/linux/ubuntu/</a>), using the
command:</p>
<ul>
<li>sudo apt install postgresql-15 postgis postgresql-15-postgis-3</li>
</ul>
<p>Another ppa I have in use is ubuntugis-unstable, it also includes
postgis - could this be a reason for the problem?</p>
<p>Help would be greatly appreciated.</p>
