Your system is WAY outdated. Support for stoneage 3.4.y has been dropped almost two years ago. Also Xenial is no longer supported.

What should I update to? I would like to keep as much of the settings if possible.

There is no procedure to update either the firmware package from this state to an up-to-date version neither the userspace. If you want to upgrade you have to start over.
