I’ve started using Let’s Encrypt<\/a> for the SSL certificates a while back. \u00a0I installed it<\/a> on all the web servers, irrelevant of the need for SSL, just to have it there, when I need it (thanks to this Ansible role<\/a>). \u00a0One of those old web servers needed an SSL certificate recently, so I thought it’d be no problem to generate one.<\/p>\n

But I was wrong. The letsencrypt-auto<\/em> tool got outdated and was failing to execute, throwing some Python exception about missing zope.interface<\/em> module. \u00a0A quick Google search brought this StackOverflow discussion<\/a>, with the exact issue I was having.<\/p>\n

\r\nTraceback (most recent call last):\r\n  File "\/root\/.local\/share\/letsencrypt\/bin\/letsencrypt", line 7, in <module>\r\n    from certbot.main import main\r\n  File "\/root\/.local\/share\/letsencrypt\/local\/lib\/python2.7\/dist-packages\/certbot\/main.py", line 12, in <module>\r\n    import zope.component\r\n  File "\/root\/.local\/share\/letsencrypt\/local\/lib\/python2.7\/dist-packages\/zope\/component\/__init__.py", line 16, in <module>\r\n    from zope.interface import Interface\r\nImportError: No module named interface\r\n<\/pre>\n
However, the solution didn’t fix the problem for me:<\/p>\n
\r\nunset PYTHON_INSTALL_LAYOUT\r\n\/opt\/letsencrypt\/letsencrypt-auto -v\r\n<\/pre>\n
Even pulling the updated version from the GitHub repository<\/a> didn’t solve it.<\/p>\n
After poking around for a while more, I found this bug report<\/a> from the last year, which solved my problem.<\/p>\n
I recommend:<\/p>\n
    \n
  1. Running rm -rf \/root\/.local\/share\/letsencrypt<\/strong>. This removes your installation of letsencrypt, but keeps all configuration files, certificates, logs, etc.<\/li>\n
  2. Make sure you have an up to date copy of letsencrypt-auto. It can be found here.<\/li>\n
  3. Run letsencrypt-auto again.<\/li>\n<\/ol>\n
    If you get the same behavior, you can try installing zope.interface manually by running:<\/p>\n
    \/root\/.local\/share\/letsencrypt\/bin\/pip install zope.interface<\/code><\/p><\/blockquote>\n
    Hopefully, next time I’ll remember to search my blog’s archives …<\/p>\n
    Update (May 31, 2017)<\/strong>: check out my brother’s follow up post<\/a> with even better way of fixing this issue.<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
