Trouble installing on Ubuntu. Cannot run as sudo

[vince-p]

I'm running a clean install of ubuntu server.

I used the following commands to install dua:
curl -LSfs https://raw.githubusercontent.com/byron/dua-cli/master/ci/install.sh | \ sh -s -- --git byron/dua-cli --target x86_64-unknown-linux-musl --crate dua --tag v2.20.1

That ran successfully but the command 'dua' did not work, I got a "command not found error".
I added ~/.cargo/bin to my PATH, and now it does run.

But I cannot do 'sudo dua'. I again get 'command not found'.

Is there a way to install on Ubuntu so that I dont have to worry about paths and can run the program as sudo?
Alternately, how can run the command as sudo in my current situation.
Thanks

I also tried deleting everything, installing rustup and installing through cargo.
This results in the same situation: dua runs as my user but when I try 'sudo dua' i get 'command not found'
