Again, Debian 9. Doing "git gcc-backport a4aca1edaf37d43" on releases/gcc-10 gave me:

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. Perhaps this is a different incantation. Are the dependencies listed somewhere? brgds, H-P
