Solution

I had 2 cargo installed. One with apt install ; the other one with snap (called with rustup.cargo). cargo --version was wayyyy old, and no way to update it apparently.
In fact, rustup installed with snap (since not available in depots) is ****.
You also have to apt remove rustc

then install rustup properly
https://rustup.rs/

and then

rustup install nightly
rustup default nightly
cargo clean
cargo build --release

you didn't follow closely enough, as the issue is that you're not on nightly rust - which is required to build eww
