Hey!

For some reason, I now get the following error message when trying to
initialize a new virtualenv:

I get the same problem with "python -m virtualenv".

Followup-For: Bug #821223

Dear Maintainer,
as already reported, I can confirm that I encounter the same bug
and identical error message, and I am therefore unable to create
a working virtual environment.

All the best
steko

Just to add more detail on the issue, I tried on a fresh sid install (with Docker) and the following works well:

the resulting "test" virtual environment is created correctly. So it would seem a problem of the Debian package and not of upstream virtualenv or pip.

Thanks a lot for maintaining this package,

Can you please report the output of `dpkg-query -W python-pip-whl`, both if
virtualenv works and doesn't work for you?
