[GRASS-user] error in g.extension, add-ons not written in GUI

[Veronica Andreo]

Hi all,

I just compiled grass77 in a Linux Mint 19.1 Cinamon laptop following the
instructions here:
https://grasswiki.osgeo.org/wiki/Compile_and_Install#Linux_Mint

All is fine, but when we install any add-on, we get:.
g.extension r.seasons
Fetching <r.seasons> from GRASS GIS Addons repository (be patient)...

The add-on is indeed installed, but it is not added to the list of
extensions in the GUI. Is there something we are missing here or in the
instructions for Mint?? I cannot reproduce in my Fedora box with freshly
re-compiled grass77

Any hint is wellcome :)
Cheers,
Vero
