You have been subscribed to a public bug: Updated from python version 2.7 to 3.5 and removed the former from the alternatives list. It broke python-psycopg2 package so that I could not either finish installation or remove the package, and I got warnings every time I installed other packages through apt or updated apt sources, and various crashes reports on startup.
Adding python 2.7 to alternatives again, with priority set to 2 ($ sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 2) restored normal behavior, but it took me a bit to understand what to do. Maybe there could be a better warning or error message that pointed the user to the right direction.
