Installation problem with SALOME-9.9.0-UB18.04-SRC

Hi, I run ubuntu 18.04. I downloaded SALOME-9.9.0-UB18.04-SRC.tar.gz and extracted it to /opt/Salome9_9 and then tried to launch:

tar xfz SALOME-9.9.0-UB18.04-SRC.tar.gz
/opt/Salome9_9/SALOME-9.9.0-UB18.04-SRC/salome

I then get the error:
SALOME_Session_Server_No_Server: error while loading shared libraries: libgeos_c.so.1: cannot open shared object file: No such file or directory

I assume I have some missing PREREQUISITES. I then tried to find out what was missing with:
sat config SALOME-9.9.0 --check_system

I then get the error:
Failed to import the site module

What can I do next? should I install libgeos-dev and hope that that resolves my issue? or is there a more instrumental approach to troubleshoot this?

can you try first to install libgeos-c1v5 and try to run SALOME again ?

apt-file find /usr/lib/x86_64-linux-gnu/libgeos_c.so.1
libgeos-c1v5: /usr/lib/x86_64-linux-gnu/libgeos_c.so.1
apt install libgeos-c1v5

OK, thank you, installing libgeos-c1v5 seem to have solved the problem.
