rustup: Rust 1.26.0 fails to install on ARM

Looks like the nightly build resolves the issues: curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain nightly

It’s also fixed in beta

Install also did not work for me. I had to first uninstall and then install again and it worked. Thanks @rosenk !

On a new board that doesn’t already have rustup, it appears you can install 1.25.0, from scratch, using this:

curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain 1.25.0

Could this be backported to stable. It’s really bad UX for new users if the language installer fails.

EDIT I’m happy to do this if someone oks it/points me in the right direction. EDIT 2 For me, rust 1.26.1 fixes the issue.

“Some users will need to run rustup install stable instead of rustup update to make rustup avoid the missing docs component, but this should be a one-time problem.” https://blog.rust-lang.org/2018/05/29/Rust-1.26.1.html

Still having issues here on a raspberry pi w upgrading to 1.26.1

 $ rustup update stable

The 1.26.1 release isn’t quite out yet, but you can test whether it works for you with RUSTUP_DIST_SERVER=https://dev-static.rust-lang.org rustup update stable. Some users are still seeing problems, so it would be good to get wider testing to determine if there’s something further we can do to resolve this…
