It's weird because CLN plugin didn't update its Rust edition since 0.10.2. How did you install Rust and Cargo?
I honestly don't remember install neither of them.
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Is this supposed to change my cargo or rust version? Because I just executed it, and I'm still with the same error during
sudo make install. My cargo version hasn't changed, so it was probably for rust. I don't know neither of the two, but isn't the error essentially saying that I have to upgrade my cargo?
