离线安装winehq

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.

The procedure goes like this:
On the machine with internet,
add the WineHQ PPA,
then cache just the necessary packages without actually extracting them:

1
2

sudo add-apt-repository ppa:wine/wine-builds
sudo apt-get update

Then cache just the packages necessary for installing wine, without extracting them:

1
2
3

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:

1

cp -R /var/cache/apt/archives/ /media/usb-drive/deb-pkgs/

Finally, on the machine without internet, install all of the packages from the flash drive:

1
2

cd /media/usb-drive/deb-pkgs
sudo dpkg -i *.deb

The same instructions can also be used for an offline installation of the winehq-staging packages.
