** This bug has been marked a duplicate of bug 1715062 package python-six 1.10.0-3 failed to install/upgrade: subprocess installed pre-removal script returned error exit status 1 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python-defaults in Ubuntu. https://bugs.launchpad.net/bugs/1700964 Title: package python-psycopg2 2.6.1-1build2 failed to install/upgrade: sub- processo script pre-removal instalado retornou estado de saída de erro 1 Status in python-defaults package in Ubuntu: New Bug description: 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.
