This is a simple transport for downloading debian packages from a repository over i2p. It uses the built-in HTTP proxy or one you configure. It's a modified version of diocles/apt-tranport-http-golang, a plain HTTP Transport for apt.

Besides that, I think most would agree that it is simpler to use an apt transport to detect when a package should be retrieved from an i2p service. Especially in cases where the user is mixing packages from Tor, I2P, and Clearnet sources, this process can become confusing and involve configuring multiple applications along with apt. Instead, apt-transport-i2phttp works with other apt transports like apt-transport-tor and even apt-transport-i2p(A SAM based alternate i2p transport), requiring no configuration on the vast majority of systems.

To install it:

As long as you have an i2p router installed the http proxy should be enabled by default. You can just:

    make build && sudo make install

to install ./apt-transport-i2phttp to /usr/lib/apt/methods/i2p, requiring no additional configuration.

To build a proper deb of it:

Building a release is done with pbuilder to avoid building a release with packages not in the appropriate version of Debian or Ubuntu. Use pbuilder create to set up the chroot appropriate to your target distribution. Then, in the root of the repository directory, run the command debuild -s to generate a .dsc file in the parent directory. Now that you have the ,dsc file, create a build directory using mkdir -p deb/targetdistro and run pbuilder build --buildresult ./deb/stable to generate your actual deb packages. Of course, you'll have to adjust the commands to suit the target distribution. And you have to do it for every single distribution you want to build for.

I have this script stored at this gist that I use to make my life easier. It should also be pretty easy to understand. From the repository directory, run the script like:

    $pathtoscript/release.sh stable

so to build for like a whole bunch of releases(With it installed as release-pdeb in /usr/local/bin):

    release-pdeb stable
    release-pdeb testing
    release-pdeb unstable
    release-pdeb bionic
    release-pdeb eoan
    release-pdeb focal

To use it:

Adding this to your sources.list.d will configure apt to seek updates to ppa.launchpad.net/i2p-maintainers from a caching proxy at the b32 address: h2knzawve56vtiimbdsl74bmbuw7xr65xhgrdjtjnbfxxw4hsqlq.b32.i2p

    deb i2p://h2knzawve56vtiimbdsl74bmbuw7xr65xhgrdjtjnbfxxw4hsqlq.b32.i2p/ppa.launchpad.net/i2p-maintainers/i2p/ubuntu bionic main
    deb-src i2p://h2knzawve56vtiimbdsl74bmbuw7xr65xhgrdjtjnbfxxw4hsqlq.b32.i2p/ppa.launchpad.net/i2p-maintainers/i2p/ubuntu bionic main
