I've rewritten and redeployed the rustup.sh script, which is used to download and install Rust as a shell one-liner:
$ curl -sf https://static.rust-lang.org/rustup.sh | sudo sh
The new revision lives in its own repo and is based off the multirust source (and in turn the next multirust should be based off of rustup.sh), but can still be accessed via
The interface is the same. The major features added by this rewrite are the ability to correctly download the installer from release channels, and automatic signature verification. It has one regression in that the
--save flag does not currently cache downloads for later reuse, but I'll add that back soon.
Let me know if you see any other regressions.
