Thanks.  That's helpful.

Looking at debpython/namespace.py, it is supposed to prevent this from 
happening.  Not sure why it isn't yet.

I agree python-defaults is the right package for this, I don't think it's 
grave, however.

Small typo in my previous email, the .prerm script contains:

pyclean -p python-backports.ssl-match-hostname

I had another package in my clipboard, just wanted to clear that up so
there's no confusion :)

Hi. I was also affected by this bug and I managed to reproduce it.

> Why do you think that the file going missing is a python-minimal bug?

The missing file seems to be generated by the postinst script which
contains:

pycompile -p python-backports.ssl-match-hostname


But, there's also a .prerm script for this package that runs this:

pyclean -p python-backports-shutil-get-terminal-size


If you install (reinstall) those packages:

python-backports.ssl-match-hostname
python-backports-shutil-get-terminal-size

And remove either of them, you'll end up with

/usr/lib/python2.7/dist-packages/backports/__init__.py{c}

missing.


Maybe those scripts should check if those files belong to another
packages before running pyclean

There are other python-backports-* packages that probably suffer from
the same problem.

Why do you think that the file going missing is a python-minimal bug?

So (force) purging python-backports.ssl-match-hostname and reinstalling 
it fixed the isssue...


When purging dpkg showed the following lines:

Suppression de python-backports.ssl-match-hostname (3.5.0.1-1) ...
E: namespace:121: cannot remove 
/usr/lib/python2.7/dist-packages/backports/__init__.py


Somehow, /usr/lib/python2.7/dist-packages/backports/__init__.py was not 
existing on the system

Package: python-docker
Version: 2.5.1-1
Severity: grave

Hi,

Seems that python-docker completely fails:

>>> import docker
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.7/dist-packages/docker/__init__.py", line 2, in

21, in 
from backports.ssl_match_hostname import match_hostname
ImportError: No module named backports.ssl_match_hostname

As you can see below, python-backports.ssl-match-hostname is installed

Kind regards,
