Was testing rustup on a very minimal Debian installation and got errors during the install process (error occurred in
install.sh
of the Rust nightly.)Noticed that Rustup was downloading the i686 nightly instead of x86-64. Installing
file
fixed the problem, and this patch adds the probe to ensure file is installed before attempting to use it.There may still be an issue with the i686 installation, I did not investigate further.
