Welcome to Rust.

WARNING: This script appears to be running as root. While it will work
correctly, it is no longer necessary for rustup.sh to run as root.

This script will download the Rust compiler and its package manager, Cargo, and
install them to /usr/local. You may install elsewhere by running this script
with the --prefix=<path> option.

The installer will run under 'sudo' and may ask you for your password. If you do
not want the script to run 'sudo' then pass it the --disable-sudo flag.

You may uninstall later by running /usr/local/lib/rustlib/uninstall.sh,
or by running this script again with the --uninstall flag.

I am using my Lubuntu with Turkish language. I downloaded linux binary and i ran install.sh with LANG=en_US parameter.

$ sudo LANG=en_US ./install.sh

It fixed the problem.
