Installer not working: "error: could not download file from" #3513

Problem

I'm facing the same issue as described here: #1328 #2929

My setup: WSL2 (Ubuntu), no proxy, no VPN, etc.

Steps

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

Possible Solution(s)

This fixed it for me: #1328 (comment)

1. $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh --> ❌ error: could not download file from ... operation timed out: operation timed out

2. PS curl https://sh.rustup.rs --> ✅ works

3. $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh --> ❌ error: could not download file from 'https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256' to '/home/pepper/.rustup/tmp/kilcw5u__cqm0aow_file': failed to make network request: error sending request for url (https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256): operation timed out: operation timed out

4. PS curl https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256 --> ✅ works

5. $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh --> ✅ works: "Rust is installed now. Great!"
