I just installed cargo before this attempt, using apt. That pulled with it the following:
¤ cargo amd64 0.52.0-0ubuntu1~18.04.1
¤ rustc amd64 1.51.0+dfsg1+llvm-1~exp3ubuntu1~18.04.1
¤ libstd-rust-dev amd64 1.51.0+dfsg1+llvm-1~exp3ubuntu1~18.04.1
¤ libstd-rust-1.51 amd64 1.51.0+dfsg1+llvm-1~exp3ubuntu1~18.04.1

Can I do anything to help you debug this?

It looks like that's an older version of Rust, there's a good chance an update will fix it. Try running the following and then try installing lazycli again:

rustup update

Thanks! Had to uninstall cargo and rustc, I had installed via apt. When installing as described on https://rustup.rs/ instead it worked fine. Will close.
