This is subprocess.Popen.__init__, which is part of the Python standard library. https://docs.python.org/3.6/library/subprocess.html#popen-constructor states: "New in version 3.6: 'encoding' and 'errors' were added." Hence it looks like git-backport.py is implicitly assuming Python 3.6 or later. > The commit looked fine with a "(cherry picked from commit > a4aca1edaf37d43b2b7e9111825837a7a317b1b0)", appended to the > commit log, so I pushed it successfully (using git am on the > format-patch of this commit on another machine, so the sha above > is not the final one, but 6f49c66ed4e060c333d8bcd). > > Not sure what other information is needed, but maybe: > > $ dpkg -s python3 > Package: python3 > Status: install ok installed > Priority: optional > Section: python > Installed-Size: 67 > Maintainer: Matthias Klose <d...@debian.org> > Architecture: amd64 > Multi-Arch: allowed > Source: python3-defaults > Version: 3.5.3-1 > Replaces: python3-minimal (<< 3.1.2-2) > Provides: python3-profiler > Depends: python3.5 (>= 3.5.3-1~), libpython3-stdlib (= 3.5.3-1), dh- > python > Pre-Depends: python3-minimal (= 3.5.3-1) > Suggests: python3-doc (>= 3.5.3-1), python3-tk (>= 3.5.3-1~), > python3-venv (>= 3.5.3-1) > Description: interactive high-level object-oriented language (default > python3 version) > Python, the high-level, interactive object oriented language, > includes an extensive class library with lots of goodies for > network programming, system administration, sounds and graphics. > . > This package is a dependency package, which depends on Debian's > default > Python 3 version (currently v3.5). > Homepage: http://www.python.org/ > > FWIW, I manually did "apt-get install python3-unidiff" and > "apt-get install python3-dateutil" to deal with missing packages > in other related scripts.
