I tried using "fix missing" and that didn't work. Tried using update and I got this:

Ubuntu 16.10 is no longer supported, and the PPA is missing a needed security feature (and therefore probably should have never worked). The PPA will certainly not be updated. Ubuntu 16.10 will not be. You should first take steps to keep your computer secure by using a supported version of Ubuntu.

As soon as possible, you should upgrade to Ubuntu 17.10 (run Software Updater) or install Ubuntu 16.04 LTS over your existing Ubuntu installation (this should preserve your home folder, but make backups). You can stick with Ubuntu 16.04 LTS until April 2021, or you can update 17.10 to 18.04 LTS in April and stick with that until April 2023.

Octave is included in the Ubuntu repositories. Ubuntu 16.04 LTS contains v4.0.0, and Ubuntu 17.10 and 18.04 contain v4.2.1, which is the latest version.
