Source: python-acme Version: 0.1.0-1 Severity: serious python-acme needs at least version 0.15 of python-openssl. This is reflected in the Build-Depends, but the binary packages have an unversioned dependency on python-openssl.
Trying to use the letsencrypt client with older versions of python-openssl results in an error, see https://github.com/letsencrypt/letsencrypt/issues/885 Ansgar
