Hi Moritz,
Hi Roberta,
I'm really no expert in this domain, so just doing some educated guessing.

First of all, the importgrass.py you sent only has 72 lines, so I don't
know what the line 82 reference in your above error points to.
This is simply due to some print that I added to the code before checking the
error log.
But most importantly, I would really recommend that you upgrade to a
newer version of GRASS GIS. Current stable is 7.8. There's been a lot of
improvement in terms of python3 compatibility and maybe this is an issue
that has already been resolved.
It sounds like an issue with a variable containing a path. Apparently it
is of type NoneType...
I tried to upgrade GRASS using the repository ubuntugis unstable but it caused
some problems with the installation of postgis. Do you have another solution?

What happens when you replace '/usr/bin/python3 importgrass.py ' by, for
example '/usr/bin/grass --version', just to check if other executables
work ?
I tried to run '/usr/bin/grass --version' but I got a similar error:
File "/usr/bin/grass", line 2005, in
main()
File "/usr/bin/grass", line 1804, in main
grass_config_dir = get_grass_config_dir()
File "/usr/bin/grass", line 398, in get_grass_config_dir
directory = os.path.join(os.getenv('HOME'), grass_config_dirname)
File "/usr/lib/python2.7/posixpath.py", line 70, in join
elif path == '' or path.endswith('/'):
AttributeError: 'NoneType' object has no attribute 'endswith'

Thanks again!
