New submission from Jeroen Van Goey:
I installed Python 3.6 from J Fernyhough's PPA by doing
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
I made a string, using the new literal string interpolation, but I supplied an
invalid format specifier. I not only got the expected "ValueError: Invalid
format specifier", but also the unexpected "ModuleNotFoundError: No module
named 'apt_pkg'".
$ python3.6
Python 3.6.0 (default, Dec 29 2016, 21:40:36)
[GCC 5.4.1 20161202] on linux
Type "help", "copyright", "credits" or "license" for more information.
