Can't install anything with pip (connection error)

See original GitHub issue

Hello,

I’m running Arch Linux on Raspberry Pi with python 3.4.1-1 and python-pip 1.5.6-1 and I can’t install anything.

For example, I can successfuly create virtualenv test:

Using base prefix '/usr'
New python executable in test/bin/python3
Also creating executable in test/bin/python
Installing setuptools, pip... done.

then I activate venv: source test/bin/activate and check packages pip list

pip (1.5.5)
setuptools (3.4.4)

And then when I try to search e.g. pytz using pip search pytz it works OK:

pytz                      - World timezone definitions, modern and historical
django-datetimezone-field - A Django app providing database and form fields for split datetime/time and pytz timezone objects.
gaepytz                   - A version of pytz that works well on Google App Engine.
django-timezone-field     - A Django app providing database and form fields for pytz timezone objects.
pytzpure                  - A pure-Python version of PYTZ (timezones).
mytz                      - A drop-in replacement for pytz.

but when I run pip install pytz --verbose I get:

Storing debug log for failure in /root/.pip/pip.log

Of course it doesn’t work with any package. Apart from this, device is working fine - It has working connection (it is web server and works fine, I can ping/ssh outside/inside etc.) and I’m not using proxy (it is connected right to the router).

I can (and I have to) install packages manually (download them using wget and then use pip to install them).

Thank you
