It is nearly that easy. You follow the instructions given https://geti2p.net/en/download/debian and have I2P running.

The steps are:

1. install PPA (not uncommon OBS has the same installation method)
2. apt-get install i2p i2p-keyring
3. start i2p sudo dpkg-reconfigure i2p
4. Open http://127.0.0.1:7657/ to configure i2p (optional)

Started by yours truly

Once qbittorrent has stable I2P support, then blocking sites like megaup and 1fichier will be completely useless. People will just download I2P and qbittorent, find a tracker on the darknet, and start downloading.

Wouldn’t surprise me if we were to see the rise of emule,DC++, and similar stuff over I2P.

Didn’t they destroy it in the first place?

Open your activity monitor (or hit Ctrl+Esc) and sort by CPU usage. What’s your computer doing?

Also, have you installed all necessary drivers? I’ve never had your problem, so there’s a chance you don’t have the right drivers.

Could you follow the instructions on https://linux-hardware.org/?view=howto , upload a hardware probe and share the link here?
