Some small manual to simple installing I2P on workstation.
Official instructions here: https://geti2p.net/en/download/debian
First download I2P key wich sighed packeges:
Open synaptic-settings-repositories and add two new distributions:
When you finish with it,reload synaptic that changes applied.After just search i2p,mark and install all packeges.
Start router, i2prouter start.
Personally i have an error now,earlier seems to be fine,maybe thats because of new i2p release 0.9.10.1 or updated whonix 7.7.2,maybe you guys tryed if you need i2p installed.
