This happened after I tried to upgrade to Ubuntu 16.04.3 LTS by running 'do-release-upgrade'

You're using Debian repos on Ubuntu and you haven't replaced codename with the codename of your version (which can be found at https://nginx.org/en/linux_packages.html#distributions)

You can remove the nginx lines from sources.list(.d) and follow the instructions on the nginx package install guide to add the repository properly and resolve the error.

If you would, please try running:

rm -rf /var/lib/apt/lists/*

Once ran, please try running apt-get update once again. Generally, that'll solve the issue, as long as the repositories in your sources.list file are correct and have not been modified.

...

When running do-release-upgrade, you generally need to modify the source repositories so that the command pulls from the release you want to upgrade to. This isn't generally a command I would run on a production server though as it can have some unintended side effects and require quite a bit of troubleshooting.

When it comes to major releases, such as upgrading from 14.04 to 16.04, it's often best to deploy a new server with 16.04 and migrate data over to it. It's a bit of a manual process, though it'll ensure everything runs smoothly.

    Thank you guys for the quick response. After removing the nginx lines from sources.list I now get a warning:

    W: Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-max
    W: Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-min
    W: You may want to run apt-get update to correct these problems

    Should I be concerned with these or can I safely ignore? Thanks again!
