I’m trying to install Letsencrypt on a DigitalOcean Ubuntu 14.04 instance. Everything looks fine when I run the letsencrypt-auto command but then I get:
Command “/root/.local/share/letsencrypt/bin/python2.7 -c “import setuptools, tokenize;file=’/tmp/pip-build-d2GoNN/cryptography/setup.py’;exec(compile(getattr(tokenize, ‘open’, open)(file).read().replace(’\r\n’, ‘\n’), file, ‘exec’))” install --record /tmp/pip-vmLs2W-record/install-record.txt --single-version-externally-managed --compile --install-headers /root/.local/share/letsencrypt/include/site/python2.7/cryptography” failed with error code 1 in /tmp/pip-build-d2GoNN/cryptography
Any suggestions?
