rustup: Rustup installation fails on raspberry pi 4 (raspbian)

Problem

I need the latest version ot rustc to install the last release of home assistant, but it seems that the executables for a wrong architecture were downloaded using rustup default installation.

As a result I get

error: command failed: ‘rustc’: No such file or directory (os error 2)

Help or suggestions?

Thanks, Massimo

Welcome to Rust!

This will download and install the official compiler for the Rust programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup home directory, located at:

/home/homeassistant/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

/home/homeassistant/.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to Cargo’s bin directory, located at:

/home/homeassistant/.cargo/bin

This path will then be added to your PATH environment variable by modifying the profile files located at:

/home/homeassistant/.profile /home/homeassistant/.bashrc

You can uninstall at any time with rustup self uninstall and these changes will be reverted.

Current installation options:

default host triple: aarch64-unknown-linux-gnu default toolchain: stable (default) profile: default modify PATH variable: yes

1. Proceed with installation (default)
2. Customize installation
3. Cancel installation

I’m going to ask you the value of each of these installation options. You may simply press the Enter key to leave unchanged.

Default host triple? [aarch64-unknown-linux-gnu]

Default toolchain? (stable/beta/nightly/none) [stable]

Profile (which tools and data to install)? (minimal/default/complete) [default]

Modify PATH variable? (Y/n)

Current installation options:

default host triple: aarch64-unknown-linux-gnu default toolchain: stable profile: default modify PATH variable: yes

1. Proceed with installation (default)
2. Customize installation
3. Cancel installation

Rust is installed now. Great!

To get started you may need to restart your current shell. This would reload your PATH environment variable to include Cargo’s bin directory ($HOME/.cargo/bin).

To configure your current shell, run: source “$HOME/.cargo/env” (homeassistant) homeassistant@raspix:/srv/homeassistant $ source “$HOME/.cargo/env” (homeassistant) homeassistant@raspix:/srv/homeassistant $ rustup --version rustup 1.26.0 (5af9b9484 2023-04-05) info: This is the version for the rustup toolchain manager, not the rustc compiler. info: The currently active rustc version is (error reading rustc version) (homeassistant) homeassistant@raspix:/srv/homeassistant $ rustc --version error: command failed: ‘rustc’: No such file or directory (os error 2) (homeassistant) homeassistant@raspix:/srv/homeassistant $
