System

• xuname: Void 5.10.19_1 x86_64 AuthenticAMD uptodate rFFFF
• package: grass-7.6.1_4

Expected behavior

Executing grass76 should start the GUI of the program

Actual behavior

Starting GRASS GIS...
WARNING: GRASS GUI not found. Please check your installation.
Switching to text based interface mode.

Steps to reproduce the behavior

$ sudo xbps-install grass
$ grass76

Causes

I have found two causes:
a) /usr/bin/grass76 has at line 105 hardcoded a path for the lib files that does not exist as it is different than that of the installation
b) if I understood correctly, it requires wxpython v2

Probable solution

Upgrade version to the latest, I have found a fork by @Nyx70 https://github.com/Nyx70/void-packages/blob/qgis/srcpkgs/grass/
