Problem

I am trying to install rust on another usb device using rustup. I used CARGO_HOME and RUSTUP_HOME env variables to setup rustup path to be on the specific usb drive, when I install rustup it did not install and showed this error I used sudo before sh and it installed, but it didnt install any of the tool chains, so I found ansnwer to stack overflow that advised to type in the terminal "rustup install stable" So I did and it showed this error again, I tried again with sudo still showing this error

Steps

install rust with rustup on a differnet usb drive or maybe even path

add environment variables RUSTUP_HOME and CARGO_HOME to the path your installing to

run curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sudo sh

then when installed change the option of changing the path variable to no
once installed add rustup to path
then use rustup install stable to install rust

99% likelyhood that your USB device is formatted with a FAT variant filesystem, which do not support links. If you reformat it with ext4 / btrfs or some other regular filesystem, this should work fine.
