I solved this with pip install libtorrent==1.2.15. Installing the latest version (2.0.5) won't work because of some cpp binding error (their fault).

@2ico unfortunately there is no easy way to install libtorrent and it differs from OS to OS.

That is why we put the information regarding dependency installation (libtorrent included) to the following documentation: https://github.com/Tribler/tribler/tree/main/doc/development

Normally you could not install libtorrent via pip.

For example, for Linux you have to run:

sudo apt install python3-libtorrent

For macOS:

brew install libtorrent-rasterbar

For Windows: https://github.com/Tribler/tribler/blob/main/doc/development/development_on_windows.rst#libtorrent

Regarding the 2.x.y version of libtorrent, we don't support it yet.

Yes, then I suggest you link those doc pages in https://github.com/Tribler/tribler/blob/9ec9fd8aae2b6e10aa472757e8c5b819f5f3d439/src/README.md.
Right now it has a broken url to https://github.com/Tribler/tribler#setting-up-your-development-environment

@2ico thank you for pointing this out.
