I2P Easy Install Bundle for Mac OS X
i2pinstall_2.2.0.jarMirror:
sigterm.no select alternate mirror sig The most reliable way to launch the installer is from a terminal like this: java -jar i2pinstall_2.2.0.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_2.2.0.jar" file or right-clicking the file and selecting "Open with Java". Unfortunately, this behaviour is difficult to predict.
Command line (headless) install:
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 commandjava -jar i2pinstall_2.2.0.jar -console to follow the install procedure in your terminal. 
Packages for Debian & Ubuntu are available. 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.
