UnicodeDecodeError 0xe2 in letsencrypt-auto

I just got this error on Laravel Forge. Thought I should paste it here.

I have this too. Related:

Same.

Same issue here on 3.16.0-46-generic #6214.04.1-Ubuntu. This happened while trying to build OpenSSL (1.0.2g-1+deb.sury.orgtrusty+1).

Thank you for posting your solution of downgrading, @singlow. Your solution worked for me. Those of you who are still looking for a temporary solution, check this out.

certbot/certbot#2588

Can you try upgrading to a newer version of pip and seeing if the problem goes away? I suspect 1.5.4 is causing the unicode error (and then the C build error is a separate thing).

[erikrose]

All of you tracking this issue might also (and more easily) try setting the env var LC_ALL=C while running letsencrypt-auto and see if that helps while we work on a better fix:

LC_ALL=C letsencrypt-auto ...

[erikrose]

I'm going to assume this is a pip error until somebody shows it still happens under the latest pip (in which case please reopen). We're working around it in certbot/certbot#2596.
