You are using an outdated version of youtube-dl.

It looks like you installed youtube-dl with a package manager (something like apt-get or pip). You can use that package manager to update youtube-dl (you may need to contact the package maintainer though, and request an update).

Alternatively, uninstall the youtube-dl package and follow our manual installation instructions. From then on, you'll be able to update with sudo youtube-dl -U.
