aptproxy

aptproxy

aptproxy is a simple minimal HTTP cache for APT package repositories. It has almost no features:

• supports the standard HTTP proxy protocol
• supports the CONNECT protocol to avoid breaking misconfigured clients that might try to connect to https sites through it, though it won't cache anything in that case
• it can send conditional GET requests for Release files and such
• it won't do conditional requests for .deb packages because it assumes those to be immutable
• it is not a real HTTP caching proxy because it does not understand the Vary header
• it will prevent connections to localhost or to private network ranges, including domains that resolve to those addresses
• multiple concurrent requests for the same URL will result in a single upstream request

Installation

All installation methods involve building aptproxy from source, so you're going to need a Go environment installed on your computer. On a Debian system:

sudo apt install golang

From the source repo

To build the package you can clone this repository and run

go build .

Then install the resulting aptproxy binary wherever you want.

From source via go install

You don't even need to clone this repository by installing the tool with:

go install git.autistici.org/pipelines/tools/aptproxy@latest

This will result in an aptproxy binary likely appearing in ~/go/bin.

Debian package

The above methods aren't really enough for a system daemon, which is why we recommend installing aptproxy as a Debian package. You can build the package, after having cloned this repository, with the standard Debian developer tools:

sudo apt install dpkg-dev debhelper dh-golang fakeroot
dpkg-buildpackage -rfakeroot -us -uc -b
sudo dpkg -i ../aptproxy*.deb
