Hi Markus,

Thank you for your reply and correction. But no thing has changed on my Grass 
7.8.3 / Ubuntu 20.10, and it's still working on may Grass 7.69 / Debian Buster 
(see console below)
Yes:

- GRASS GIS 7.6 uses Python 2
- GRASS GIS 7.8 uses Python 3
I wrote 7.69 but it's 7.9...

It's curious that Grass say "...not found" on every script, while copying the 
file in addons/ ?
Here I didn't get that error but mainly the one with the wrong
formatting. The "... not found" might be a secondary error while the
original error message isn't visible (for whatever reason).

Let me suggest that you update all Python script to Python 3 (there is
the "2to3" script as well as "autopep8" and others for that purpose).
Once done, perhaps the errors you get are gone?

Ok I will update at least one script, and remove the other for testing (I know I must update all). But I'm surprised because scripts could be executed with File>Launch script...
I wil tell you soon.

Thank you for your help.
Cheers,
Frank

Hello,

I've installed GRASS 7.8.3 on Ubuntu 20.10 (groovy) and when I try to install 
my own python script, the message is :

Fetching <r.wtg> from 
</media/zephyr/ress/informatique/scripts/grass/scripts/r.wtg> (be patient)...
Compiling...
/bin/sh: 1:

/tmp/grass7-geophom-78286/tmp1tw0ncyb/r.wtg/scripts/r.wtg.visibility.conv: not 
found

...

Do you have any idea that problem ?

This is somehow hard to say - is the addon available for testing?

For posterity:

I received the addon offlist. Some files showed Python 3 syntax
errors, fixed with "autopep8" and now the installation works (for me).

cheers,
Markus
