Using an apt cache will greatly improve build speed when building several times in a row (e.g. when debugging, during development).
If you are interested, click on Expand on the right.
The following torified apt-cacher-ng setup only has to be applied, if you are building using onion apt sources using
However, if you are building behind a Tor transparent proxy such as Whonix-Gateway ™, you can use the simpler clearnet apt-cacher-ng instructions below instead.
Note, this neither torifies all of the build script's connections nor hides Tor from your ISP!
Install apt-cacher-ng-, torsocks and tor.
sudo apt-get install apt-cacher-ng torsocks tor
Create folder apt-cacher-ng systemd drop-in folder
sudo mkdir -p /lib/systemd/system/apt-cacher-ng.service.d
/lib/systemd/system/apt-cacher-ng.service.d/50_user.conf in an editor with root rights.

sudoedit for better security [archive]. This is an example and other tools could also achieve the same goal. If this example does not work for you or if you are not using Whonix, please refer to this link.
ExecStart=torsocks /usr/sbin/apt-cacher-ng SocketPath=/run/apt-cacher-ng/socket -c /etc/apt-cacher-ng ForeGround=1
sudo systemctl daemon-reload
sudo systemctl apt-cacher-ng restart
sudo apt-get install apt-cacher-ng
Be sure to have a firewall, so the whole internet can not use the apt-cacher-ng service.
REPO_PROXY=http://127.0.0.1:3142 [archive] before the build command.
sudo REPO_PROXY=http://127.0.0.1:3142 ./whonix_build ...
When building inside a non-Whonix VM, an apt cache can be used on the host. In that case, adjust the IP accordingly and manually test that it is reachable. When building inside a (Whonix ™) VM, just install the apt cache inside the VM and point to a localhost apt cache.
From 220.127.116.11.7-developers-only and above Whonix automatically uses apt-cacher-ng.
