Debian I2P Packages

Debian Sid, Ubuntu Bionic 18.04

I2P is available in the official repositories for Ubuntu Bionic 18.04 and Debian Sid. Install the "i2p" package using your package manager, as you would any other package. The instructions below are not required.

Debian Stretch and older, Ubuntu Artful 17.10 and older

The Debian packages have been tested and should work on x86/x86_64 platforms running:

Ubuntu (Precise 12.04 and newer)
Mint
Debian Linux (Wheezy and newer)
Knoppix

The I2P packages may work on systems not listed above. Please report any issues with these packages on Trac at https://trac.i2p2.de.

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

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.
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.
You are now ready to install I2P!
sudo apt-get install i2p

Adding the PPA Using Synaptic

Open Synaptic (System -> Administration -> Synaptic Package Manager).
Once Synaptic opens, select Repositories from the Settings menu.
Click the Other Sources tab and click Add. Paste ppa:i2p-maintainers/i2p into the APT-line field and click Add Source. Click the Close button then Reload.
In the Quick Filter box, type in i2p and press enter. When i2p is returned in the results list, right click i2p and select Mark for Installation. After doing so you may see a Mark additional required changes? popup. If so, click Mark then Apply.

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 include amd64, i386, armel, armhf (for Raspbian).

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).

Ensure that apt-transport-https and curl are installed.

    
    sudo apt-get update
    sudo apt-get install apt-transport-https curl

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, add lines like the following to /etc/apt/sources.list.d/i2p.list.

For Stretch (stable):
```
    deb https://deb.i2p2.de/ stretch main
    deb-src https://deb.i2p2.de/ stretch main
```
For Jessie (old-stable):
```
    deb https://deb.i2p2.de/ jessie main
    deb-src https://deb.i2p2.de/ jessie main
```
For Wheezy (obsolete):
```
    deb https://deb.i2p2.de/ wheezy main
    deb-src https://deb.i2p2.de/ wheezy main
```
Note: If you are running Debian Sid (testing), then you can install I2P directly from Debian's main repository:
```
  sudo apt-get install i2p
  
```

Download the key used to sign the repository:


  curl -o i2p-debian-repo.key.asc https://geti2p.net/_static/i2p-debian-repo.key.asc

Check the fingerprint and owner of the key without importing anything:

    
  gpg -n --import --import-options import-show i2p-debian-repo.key.asc

Add the key to APT's keyring:

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

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.

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.
