On Windows, installing I2P is easy.
On Linux… not so much. That’s because Linux isn’t Linux. There’s a Debian package, but OpenSuse is its own thing. Is there a way to get I2P, Snark, etc. up and running there without having to jump through too many hoops?
Yes, there is a jar file on the main website that works just fine. Also i2pd is in the tumbleweed repo.
