rustup: error: could not download file from ...

windows10 Internet connection has no problem

Welcome to Rust!

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

It will add the cargo, rustc, rustup and other commands to Cargo's bin
directory, located at:

  C:\Users\xxxx\.cargo\bin

This path will then be added to your PATH environment variable by modifying the
HKEY_CURRENT_USER/Environment/PATH registry key.

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

Current installation options:

   default host triple: x86_64-pc-windows-msvc
     default toolchain: stable
  modify PATH variable: yes

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

that’s my first install the Rust program language and I can assess to the office website.but this problem still exist.

It worked after I disabled network proxy…

Any updates to solution for this issue? I’m on Ubuntu 20.04.4 LTS. And I am getting a “unable to get local issuer certificate” error when trying to install with the following command:

curl --proto ‘=https’ --tlsv1.2 -sSf https://sh.rustup.rs | sh

I have strat Tor ( service tor start ) of course after installing the Tor. Then install Rust.

@kinnison Thank you for your suggestion. Snapcraft environment seems to use proxy. I ran some test script on the environment. rustup with curl-backend is OK, and rustup with reqwest-backend is NG.
