FTR: the day this PEP asks us to point /usr/bin/python to python3 is the day I start ignoring it, to say the least. > I don't think there is enough time to replace all python shebangs to python2 > in > time for the buster release, however there is no harm in starting this process > now. too late, this process has already started (since dh_python2 v3.20180313) ;-P > But I'd like to get this done for buster+1, in the case we still need to > ship a Python2/2.7, so that buster+1 doesn't ship with a python command, but > maybe with a python2 command. we already ship /usr/bin/python2. Removing /usr/bin/python makes sense as well (administrators can symlink it to whatever they want once it's gone from Debian), but... > The first step is to create a set of python2* packages in python-defaults, > with > contain all the python2* symlinks, and having the python* packages depend on > those python2 packages. This change itself is a no-op and shouldn't affect > anything. > > As a second step change the dh_python2 (in python-defaults), and dh-python to > generate dependencies on python2 instead of python, and replacing the shebang > from python to python2. > > This should cover the majority of packages to replace dependencies on python > with dependencies on python2. There are packages which don't check for > python2, > so these probably need adjustments. But again, the goal for buster+1 is to > ship > as few Python2 dependent packages as possible, if any. this is useless. What will we gain by renaming packages? I refuse to do that work! The only message it sends is that we don't think /usr/bin/python or python package is Python 2.7 anymore and that's definitely not the message I want to send. > The third step for buster+1 would be to drop the set of python* packages from > python-defaults. if we manage to remove Python 2.7 from Buster+1, all python-* packages¹ will be gone, including python-defaults so why additional work?
