[openstack-dev] Tox run failure during installation of dependencies in requirements

Hi Igor /Matthieu,

I am getting random connection timeouts to pypi.python.org with my machine behind the proxy when trying to run

Tox –e pep8

Dependency installation fails with the stack trace posted below.

However, similar issue does not occur when I use run_tests.sh to run the same set of tests.

My machine is able to reach pypi.python.org.  Some packages are getting installed while doing some others,

It fails as below.

It looks like am hitting the problem as here, but the solution proposed there isn’t working for me.

Actually the same question, what is wrong with Tox now?

Recently , the Tox runs started to fail in my workspace.

It fails consistently during installing dependencies with the following.

The TOX was earlier running in the same workspace successfully on the machine

even though we were behind the proxy.

Could you please advise on how to resolve this problem?
