[dino99 (9d9)]

python3.4 has been removed now from 16.04; so start cleaning the system:

sudo apt-get autoremove

then 'findutils' has been upgraded, and try to remove everything related to python3.4, but fails to do it cleanly itself.

The problem is that ubuntu-make still depends on python3.4 ...

I cleaned my system and deleted the folder as you mentioned in your post:

sudo apt-get install ubuntu-make
