This is a Vagrant Environment for a APT Caching Proxy server using the Apt-Cacher NG daemon.
Install the Ubuntu 20.04 box.
Run vagrant up --no-destroy-on-error cache to launch the APT Caching Proxy server.
Run vagrant up --no-destroy-on-error ubuntu to launch an Ubuntu client configured to use the cache server.
Visit http://10.10.10.3:3142/acng-report.html and click the "Count Data"
button to see the cache statistics. You'll notice a lot of cache misses.
The next client runs will have an improved cache efficiency and will be
a lot faster. To see that happening, re-create the ubuntu client (and
also re-check the cache statistics page):
vagrant destroy -f ubuntu
vagrant up --no-destroy-on-error ubuntu
