Updating the package list

After adding the repo to apt, update the package list with

    sudo apt-get update

APT will likely complain about a missing key. If it does you can resolve this by running the following:

    sudo apt-get install i2p-keyring && apt-get update

Alternately, you may download the key here and then do:

    sudo apt-key add i2p-debian-repo.key.asc

Packages in Jessie (Debian's stable distribution, released 2015-04-25)

These packages will work in Debian Jessie (stable). Packages for Unstable are below.

anoncoin-qt (0.8.5.6-1+b1, main) - peer-to-peer network based digital currency - Qt GUI
Binary for arch amd64 (1.7 MB), i386 (1.8 MB)

Anoncoin is a free open source peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending. Anoncoin is a fork of Bitcoin.

Full transaction history is stored locally at each client. This requires 200 MB+ of space, slowly growing.

This package provides Anoncoin-Qt, a GUI for Anoncoin based on Qt.
