Базовые приложения Ubuntu для Ubuntu 16.04

Когда я пытался следовать ответу на то, Как Вы устанавливаете Касание Ubuntu Coreapps?, это не работает над Ubuntu 16.04. После того, как я работал sudo apt update, Я получил это:

Reading package lists... Done

И когда я пытался установить:

sudo apt-get install ubuntu-sdk touch-coreapps

Существует ли обновленный способ сделать это?
