Hi @ryoung,

This can happen if you try to install Certbot to your system using pip. There is a warning against doing so in the documentation. It can easily break due to the way Linux systems manage Python packages.

The best way to install Certbot is to use the instructions from You may want to remove the /usr/local/bin/certbot file so that it does not interfere with the working installation.

Unfortunately I didn't install with pip, but with apt.

However, once I uninstalled everything I was able to run the certbot command from the user/bin.




/usr/bin/certbot comes from apt, but /usr/local/bin/certbot definitely comes from pip.

I think the /usr/local/bin/ has priority in your path on Ubuntu; it may have been taking priority over the one from apt.

Glad to hear you got it working.
