[GRASS-dev] Location creation failure in docker with latest grass trunk version

[Nikos Alexandris]

Hi, this is maybe similar to ticket #3693 [0].

@neteler In [0], the first example to create a Location, is performed as
root. Curious, why so? Why not as a simple user?

I just try to update my grassyan Dockerfile [0] and it fails at the
point of creating a Location, for the sake of testing. I don't know if
this is relevant with what is reported in ticket #3693:

```

Don't mind the misleading `temporary_Mapset` name, it should be
`temporary_Location` instead. Even interactively, creating a Location
will fail too:
