Let’s Encrypt<\/a> has only experimental support for the Amazon Linux AMI<\/a>, so it’s kind of expected to have issues once in a while.   Here’s one I came across today:<\/p>\n

\n# \/opt\/letsencrypt\/certbot-auto renew\nCreating virtual environment...\nInstalling Python packages...\nInstallation succeeded.\nTraceback (most recent call last):\nFile "\/root\/.local\/share\/letsencrypt\/bin\/letsencrypt", line 7, in &lt;module&gt;\nfrom certbot.main import main\nFile "\/root\/.local\/share\/letsencrypt\/local\/lib\/python2.7\/dist-packages\/certbot\/main.py", line 12, in &lt;module&gt;\nimport zope.component\nFile "\/root\/.local\/share\/letsencrypt\/local\/lib\/python2.7\/dist-packages\/zope\/component\/__init__.py", line 16, in &lt;module&gt;\nfrom zope.interface import Interface\nImportError: No module named interface\n<\/pre>\n
My first though was to install the system updates. It looks like something is off in the Python-land. But even after the “yum update<\/em>” was done, the issue was still there. A quick Google search later, thanks to the this GitHub issue<\/a> and this comment<\/a>, the solution is the following:<\/p>\n
\npip install pip --upgrade\npip install virtualenv --upgrade\nvirtualenv -p \/usr\/bin\/python27 venv27\n<\/pre>\n
Running the renewal of the certificates works as expected after this.<\/p>\n
P.S.: I wish we had fewer package and dependency managers in the world…<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
