Debian I2P Packages

Debian or Ubuntu, All Versions

The Debian packages should work on most platforms running: The I2P packages may work on systems not listed above. Please report any issues with these packages on Gitlab at i2p.i2p.
  • Option 1: Recent versions of Ubuntu and its derivatives (Try this if you're not using Debian)
  • Option 2: Debian (including Debian-derivatives)

Instructions for Ubuntu and derivatives like Linux Mint & Trisquel

Adding the PPA via the command line and installing I2P
  1. Open a terminal and enter:
        sudo apt-add-repository ppa:i2p-maintainers/i2p
    This command will add the PPA to /etc/apt/sources.list.d and fetch the gpg key that the repository has been signed with. The GPG key ensures that the packages have not been tampered with since being built.
  2. Notify your package manager of the new PPA by entering:
        sudo apt-get update
    This command will retrieve the latest list of software from each repository that is enabled on your system, including the I2P PPA that was added with the earlier command.
  3. You are now ready to install I2P!
        sudo apt-get install i2p
Adding the PPA Using the Software Center
  1. Open "Software and Updates" via the applications menu.
  2. Select the "Other Software" tab and click the "Add" button at the bottom to configure the PPA.
  3. Add the PPA by pasting the URL: ppa:i2p-maintainers/i2p into the PPA dialog.
  4. Download the repository information with the "Reload" button.
  5. Install the I2P software using the "Software" tool from the applications menu.
After the installation process completes you can move on to the next part of starting I2P and configuring it for your system.

Instructions for Debian

Currently supported architectures: amd64, i386, armhf, arm64, powerpc, ppc64el, s390x

Note: The steps below should be performed with root access (i.e., switching user to root with su or by prefixing each command with sudo).

    ,
  1. Ensure that apt-transport-https, curl, lsb-release are installed.
        
        sudo apt-get update
        sudo apt-get install apt-transport-https lsb-release curl
        
  2. Check which version of Debian you are using on this page at the Debian wiki and verify with /etc/debian_version on your system. Then, for Debian Bullseye or newer distributions run the following command to create /etc/apt/sources.list.d/i2p.list.
        
        # Use this command on Debian Bullseye or newer only.
      echo "deb [signed-by=/usr/share/keyrings/i2p-archive-keyring.gpg] https://deb.i2p2.de/ $(lsb_release -sc) main" \
      | sudo tee /etc/apt/sources.list.d/i2p.list
        
        
    if you are using Debian Buster or older distributons, use the following command instead:
        
        # Use this command on Debian Buster or older only.
      echo "deb https://deb.i2p2.de/ $(lsb_release -sc) main" \
      | sudo tee /etc/apt/sources.list.d/i2p.list
        
        
  3. Download the key used to sign the repository:
        
      curl -o i2p-archive-keyring.gpg https://geti2p.net/_static/i2p-archive-keyring.gpg
        

  4. Display the key fingerprint.
        
      gpg --keyid-format long --import --import-options show-only --with-fingerprint i2p-archive-keyring.gpg
        
        
    Verify that this key fingerprint matches the output:
        
      7840 E761 0F28 B904 7535  49D7 67EC E560 5BCF 1346
        

  5. Copy the keyring to the keyrings directory:
        
      sudo cp ~/i2p-archive-keyring.gpg /usr/share/keyrings
        
    If you are using a distribution older than Debian Buster, you will also need to symlink that key to /etc/apt/trusted.gpg.d.
        
      sudo ln -sf /usr/share/keyrings/i2p-archive-keyring.gpg /etc/apt/trusted.gpg.d/i2p-archive-keyring.gpg
        
  6. Notify your package manager of the new repository by entering:
        
      sudo apt-get update
        
    This command will retrieve the latest list of software from every repository enabled on your system, including the I2P repository added in step 1.

  7. You are now ready to install I2P! Installing the i2p-keyring package will ensure that you receive updates to the repository's GPG key.
        
      sudo apt-get install i2p i2p-keyring
        

After the installation process completes you can move on to the next part of starting I2P and configuring it for your system.

Post-install work

Using these I2P packages the I2P router can be started in the following three ways:
  • "on demand" using the i2prouter script. Simply run "i2prouter start" from a command prompt. (Note: Do not use sudo or run it as root!)
  • "on demand" without the java service wrapper (needed on non-Linux/non-x86 systems) by running "i2prouter-nowrapper". (Note: Do not use sudo or run it as root!)
  • as a service that automatically runs when your system boots, even before logging in. The service can be enabled with "dpkg-reconfigure i2p" as root or using sudo. This is the recommended means of operation.

When installing for the first time, please remember to adjust your NAT/firewall if you can. The ports to forward can be found on the network configuration page in the router console. If guidance with respect to forwarding ports is needed, you may find portforward.com to be helpful.

Please review and adjust the bandwidth settings on the configuration page, as the default settings of 96 KB/s down / 40 KB/s up are fairly conservative.
