Answer 1

I'm now getting this in $HOME/.pip/pip.log:

Could not fetch URL https://pypi.python.org/simple/: HTTP Error 403: TLSv1.2+ is required

I don't have a straightforward solution for this, but I'm mentioning it as something to watch out for before you waste time on trying some of the other solutions here.

• I'm obviously already using a https URL
• There is no proxy or firewall issue
• Using trusted-host didn't change anything (dunno where I picked this up)

For what it's worth my openssl is too old to even have ssl.OPENSSL_VERSION so maybe that's really the explanation here.

In the end, wiping my virtual environment and recreating it with virtualenv --setuptools env seems to have fixed at least the major blockers.

This is on a really old Debian box, Python 2.6.6.
