$ wine --version

To Install Wine without Internet:
To install Wine on an Ubuntu machine without internet access, you must have access to a second Ubuntu machine (or VM) with an internet connection to download the Wine .deb package and its dependencies.
On the machine with internet, add the WineHQ repository and run apt update.
Next, cache just the packages necessary for installing wine, without extracting them:
sudo apt-get clean
sudo apt-get --download-only install winehq-devel
sudo apt-get --download-only dist-upgrade

Copy all of the .deb files in /var/cache/apt/archives to a USB stick:
cp -R /var/cache/apt/archives/ /media/usb-drive/deb-pkgs/
