Hello community,
I’ve been running a new addon that I wrote and added in my local folder of available add-ons, working in Ubuntu 64bit and compiling Grass from the current release version (7.0.x).
Then decided to compile the trunk version, so when I got into Grass 73 I started having problems, namely g.extensions can’t see my local list of available addons (not installed, just available).
Basically I followed the intructions in the link [^] and repeated the steps made with the release version (under the supervision of LucaDelu).
Eventually I decided that there were too many Grass versions installed in my laptop (64 with package, 70 with release, 73 with svn) and thought that could make problems, so after some struggle with the pc I decided to get completely rid of Grass with the idea of reinstalling after a clean-up, and removed any version from my pc following the instructions here [*].
After svn up, recompiling etc now the message I get from terminal when running grass (64, 70 or 73, no matter what) is the following:
anna@anna-ubuntu:~$ grass73
Cleaning up temporary files…
Traceback (most recent call last):

not much fun, from bad to worse 
Can someone help me to find how to solve this?
And maybe to run my new addon?
Thanks!
