hi folks, I created a certificate (which works and is secure) using the following command:
certbot --apache --keep -d www.rfi.net
When I run a check on it, using “certbot certificates” I get:
Renewal configuration file /etc/letsencrypt/renewal/rfi.net.conf produced an unexpected error: cannot instantiate ctype ‘EVP_MD_CTX’ of unknown size. Skipping
This doesn’t look good for the next renewal attempt… Any ideas?
My best idea would be working with some of your Python dependencies as suggested here: https://github.com/burnash/gspread/issues/407
However that’s just from some quick poking around, so definitely vet those results against your environment.
thanks for the response, Jared. I tried this:
pip install cryptography==1.4
and got various compilation areas. I’ve a fairly clean Debian 9 (Stretch) install. Working my way through the missing libs, and installing: libffi-dev, gcc got me to the point where running the pip command above worked cleanly, and apparently I’ve successfully cargo-culted my cryptography to v1.4 Now when I run “certbot certificates” I get a meaningful output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Found the following certs:
Certificate Name: rfi.net
Expiry Date: 2017-11-29 08:45:00+00:00 (VALID: 89 days)
So I think this looks good. Many thanks for the tip!
