python3 is the default python version in Ubuntu 18.04 and
python2 won't be shipped by default on a fresh Ubuntu 18.04 installation, how can I make
python3 default after an upgrade to Ubuntu 18.04 (from 16.04). Currently, after the upgrade to
python2 it still defaulted (e.g.
python command directs to
python2 etc.). However, purging the
python package will result in removing too many packages that rely on it, so this is not an option here.
Ideally, I want to remove the
python2 dependency as much possible. Maybe the upgrade process could be designed in such a way that it checks all packages, whether they still really rely on
python2 dependencies and thereby collect all
python2 dependencies that could be replaced by an equivalent
python3 dependency (which will be resolved by the upgrade then).
