Notes Copied from an internal post : I avoided installing i2p (i2p is the first implementation of i2p, the standard router), as soon as I realised it was written in java I turned to i2pd, which is a full-featured C++ implementation of the I2P router. for the installing process, try to build from source is a better choice for me. modify the contrib/i2pd.conf then run sudo make install again to make config works.
