[GRASS-user] g.gui.rlisetup: No module named 'functions' error

[Yi Moua]

Hello,

I am using GRASS 7.8.1 installed via APT on Ubuntu 18.04.4
I would like to use g.gui.rlisetup [1], the configuration tool for r.li 
modules, but

$ g.gui.rlisetup

outputs

Traceback (most recent call last):
 ?? File "/usr/lib/grass78/scripts/g.gui.rlisetup", line 54,
in <module>
 ?????? main()
 ?? File "/usr/lib/grass78/scripts/g.gui.rlisetup", line 42,
in main
 ?????? from rlisetup.frame import RLiSetupFrame
 ?? File "/usr/lib/grass78/gui/wxpython/rlisetup/frame.py",

 ?? File "/usr/lib/grass78/gui/wxpython/rlisetup/wizard.py",
line 45, in <module>
 ?????? from functions import SamplingType, sampleAreaVector,
convertFeature
ModuleNotFoundError: No module named 'functions'

Would you know what I can do to solve this?
