An error——spatialite.so.7: undefined symbol: libiconv

hello!
When I run sentinal3B data with Polymer, the following error occurred :

(base) southocean@master:~/software/polymer-v4.12$ ./try_sential3B_data.py

Do you have any suggestion for me?
Thank you in advance!

Hi,
There seems to be an issue with the installation of gdal.
However if you want to process Sentinel3, the import of Level1_MSI is useless and can be removed.
(the line "from polymer.level1_msi import Level1_MSI" - this is for Sentinel2)
Kind regards,
François
