I'm trying to install vim 8 on ubuntu 16.10 by adding the following repository like so:
sudo add-apt-repository ppa:jonathonf/vim
after doing so apt update gets stuck
Ign:1 http://ppa.launchpad.net/jonathonf/vim/ubuntu yakkety InRelease
Err:2 http://ppa.launchpad.net/jonathonf/vim/ubuntu yakkety Release

E: The repository 'http://ppa.launchpad.net/jonathonf/vim/ubuntu yakkety Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Am I using the wrong repository? I'm following the instructions I found here.
system settings > software & updates > other software
and enable the repo there – George Udosen Jan 22 '17 at 13:46
