sudo dpkg --add-architecture i386 

Add the repository:

wget -nc https://dl.winehq.org/wine-builds/Release.key
sudo apt-key add Release.key

sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main'

Update packages:

sudo apt-get update

Then install one of the following packages:

    sudo apt-get install --install-recommends winehq-stable

    sudo apt-get install --install-recommends winehq-devel

    sudo apt-get install --install-recommends winehq-staging

this will install the latest release of wine
