The EnMAP-Box requires that your gdal installation supports GeoPackages.
I assume that your Linux installation does not, e.g. because GDAL was not compiled with GPKG support. In addition, your QGIS is quite outdated. Please install the recent QGIS (3.10 LTR or even bettern, 3.12) and try again.

The following code needs to pass the assert statement in your QGIS python shell:

from osgeo import ogr
drv = ogr.GetDriverByName('GPKG')
assert isinstance(drv, ogr.Driver)

Issue #311 was marked as a duplicate of this issue.

addresses #312 : initial dependencycheck.py checks for GDAL/OGR GPKG driver
