Had to renew my client’s server SSL certificate today (hosted on AWS EC2), the certificate was created through the magnificent certbot (let’s encrypt). The command that I ran to renew the cert was:
sudo ./certbot-auto renew
When I ran the command above, certbot was self upgraded and then I encountered the following the error:
couldn’t get currently installed version for /opt/eff.org/certbot/venv/bin/letsencrypt
To fix the issue, I just had to remove the following the offending directory, by running:
sudo rm -rf /opt/eff.org/*
Re-run of sudo ./certbot-auto renew would work then.
I sort of stumbled the solution from certbot issue comment,
the comment recommends installing certbot via pip but it wasn’t necessary in my case.
