What does this error message mean? Why is it trying to write in the
/.grass7 folder ?
Whenever you launch GRASS GIS with the grass startup script, it writes
the chosen Gisdbase/Location/Mapset info into .grass7/rc. If you launch
GRASS GIS for the first time, it first creates the directory .grass7
which is the part that fails with a permission error.
I'm no Docker expert at all, but I think you have to explicitly run the
container with parameters indicating the devices one can access from
within.
And what does the name '_' refer to?
This seems to be linked to the translation handling:
File "/usr/bin/grass", line 395, in get_grass_config_dir
_("Failed to create configuration directory '%s' with error:
%s")
Note the '_' in front of the string which marks it as a translatable
string.
There was a bug related to this a while ago, but it was fixed
(https://trac.osgeo.org/grass/ticket/3875). Maybe a locale issue ?
