how to install Network Manager on ubuntu?

Question

Can anyone help me to install network-manager-l2tp on ubuntu 16.04?

I get this error: The following packages have unmet dependencies: network-manager-l2tp : Depends: xl2tpd (>= 1.3.6+dfsg-4ubuntu0.16.04.1) but 1.3.6+dfsg-4 is to be installed

You should change your /etc/apt/sources.list file, and put the following :

deb mirror://mirrors.ubuntu.com/mirrors.txt xenial main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-updates main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-backports main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-security main restricted universe multiverse

Then in the terminal, do

sudo add-apt-repository ppa:nm-l2tp/network-manager-l2tp
sudo apt update
sudo apt install network-manager-l2tp -y
sudo apt install network-manager-l2tp-gnome -y
