Resolving the 'Cannot Import Name Appengine' Error When Using Certbot with Nginx on Ubuntu 22.04.2
In the process of setting up Certbot with Nginx on a fresh Ubuntu 22.04.2 server, I encountered a perplexing error:
cannot import name 'appengine' from 'urllib3.contrib' certbot
This blog post is dedicated to resolving this specific error. If you're facing this issue, read on as I share the solution I discovered.
Understanding the Problem
First, let's understand what's causing this error. The issue arises from a conflict between two installations of the same Python package, urllib3.
In our case, urllib3 is installed twice, once via apt (the package-handling utility in Ubuntu), and once via pip (the Python package installer). This duplication causes an import error when Certbot tries to import the 'appengine' module from 'urllib3.contrib'.
The Solution
To resolve this issue, we need to remove the urllib3 version installed by pip. Here's how you can do it:
Open your terminal.
Type in the following command and hit Enter:
pip3 uninstall urllib3
This command tells pip3 to uninstall the urllib3 package. You will be asked to confirm the uninstallation. Press y and hit Enter.
And that's it! Your Certbot should now work fine.
Verifying the Solution
To make sure that the problem is resolved, try running Certbot again. If everything goes well, you should not see the import error anymore.
Wrapping Up
In this post, we've seen how to solve a common error that occurs when installing and using Certbot with Nginx on Ubuntu 22.04.2. The error is caused by duplicate installations of the urllib3 package, and the solution is to uninstall the version installed by pip.
Remember, it's always a good practice to check for potential conflicts between apt and pip installations when you encounter similar import errors.
