[Bug 1512792] Re: Pip crashes with cryptography/cffi/openssl error

[Kai Kasurinen]

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'.

However, if you believe that this is really a bug in Ubuntu, then we
would be grateful if you would provide a more complete description of
the problem with steps to reproduce, explain why you believe this is a
bug in Ubuntu rather than a problem specific to your system, and then
change the bug status back to "New".

For local configuration issues, you can find assistance here:
