Detailed Install Guide
I2P for Mac OSX
Download the I2P for Mac DMG Bundle
I2P for Mac OSX is packaged using OSX's standard ".dmg" package type, which allows it to use Apple's built-in tools to securely, reliably, and easily install the package. It does not require Java to be installed to use.
I2P for Linux
The most reliable way to launch the installer is from a terminal like this:
java -jar i2pinstall_1.6.1.jar. This will launch the GUI installer. Depending on how your computer is set up, you may be able to start the installer by double-clicking the "i2pinstall_1.6.1.jar" file
or right-clicking the file and selecting "Open with Java". Unfortunately, this behaviour is difficult to predict.
コマンドライン (GUIなし) インストール:I2P can also be installed in a terminal environment, which may be especially useful for servers, containers, or certain virtual machines. If you wish to use the installer without a GUI, you can use the command
java -jar i2pinstall_1.6.1.jar -consoleto follow the install procedure in your terminal.
I2P for Debian and Ubuntu
I2P is available in the official repositories for Ubuntu Bionic and later, and Debian Buster and Sid. However, Debian Buster and Ubuntu Bionic (LTS) distributions will have older I2P versions. If you are not running Debian Sid or the latest Ubuntu release, use our Debian repo or Launchpad PPA to ensure you're running the latest I2P version.
I2P for Android
I2P for Docker
I2P is now available as a Docker package from the Docker Hub. You may retrieve the image by running the 'docker pull' command.
docker pull geti2p/i2p
you can fetch the source via Git from git.repo.i2p or Github.
(tar xjvf i2psource_1.6.1.tar.bz2 ; cd i2p-1.6.1 ; ant pkg) then either run the GUI installer or headless install as above.
If you are running 0.7.5 or later, your router should detect the new release. To upgrade simply click the 'Download Update' button on your router console when it appears.
Since 0.9.23, some releases are signed by str4d, whose signing key has been in the router since 0.9.9. Routers older than 0.9.9 will fail to verify update files signed by str4d, and will need to be manually updated using the process below.
- Download the file to your I2P installation directory and rename as i2pupdate.zip. (alternately, you can get the source as above and run "ant updater", then copy the resulting i2pupdate.zip to your I2P installation directory). You do NOT need to unzip the file.
