It is ignoring my changes to the repository.

Which makes sense, as sylvia is not an Ubuntu release code name, and the ROS buildfarm does not build packages for it (or at least: it doesn't store any release file for it).

Err:21 http://packages.ros.org/ros/ubuntu sylvia/main amd64 Packages

W: The repository 'http://packages.ros.org/ros/ubuntu sylvia Release' does not have a Release file.

This error also tells you that.

Linux Mint is essentially Ubuntu but the interface is different. Does anyone know how to do that?

Provided sylvia is compatible with one of Ubuntu's distributions (I haven't checked), you can try to see whether setting ROS_OS_OVERRIDE (docs) to a suitable value works. Be sure to also update your /etc/apt/sources.list.d/ros-latest.list to use the same value(s).

Finally: how to install ROS Ubuntu packages on Ubuntu derivatives has been asked a few times before. A search (with Google: site:answers.ros.org <your search terms>) should lead you to some usable information.

Edit: looks like sylvia is essentially Ubuntu Xenial. A value for ROS_OS_OVERRIDE could be: ubuntu:16.04.
