This happens because you're on an old version of Rust. Try using the latest one instead:

  1. Uninstall the packages cargo (and maybe others that got installed)
  2. Follow instructions on https://rustup.rs/

wow, rustc 1.41 is a pre-covid era version 😮 from back in the days we were commuting a lot to the office. I remember

(But don't hesitate to tell me if you still have issues! ^_^)

Fixed by installing Rust & Cargo by hand : 

sudo apt-get autoremove cargo
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Now it compiles. But my device (Roomba 976) seems not supported right now (related to https://github.com/cecton/roomba/issues/7 )
