Error running "rustup update"

[LucasPickering]

I've been seeing this error appear when trying to run rustup update inside the image (this has been happening as long as I've been using the image - about a month now).

This is running on the latest version of the image (50ee35398401, from 2018-09-30 when I pulled).

  nightly-x86_64-unknown-linux-gnu update failed - rustc 1.30.0-nightly (bb0896af1 2018-09-29)

This is the failing system call:

rename("/usr/local/rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/etc", "/usr/local/rustup/tmp/i6j4hyab3re29l9q_dir/bk") = -1 EXDEV (Invalid cross-device link)

It looks like rustup assumes that the rustup directory is the same filesystem which won't be the case in this image since parts of it are on a different layer. I'll file an issue upstream with rustup to fall back to copying if renaming fails.

Ah, this has already been filed: https://github.com/rust-lang-nursery/rustup.rs/issues/1239.

I'm going go close this in favor of that issue!

[LucasPickering]

Great, thanks for finding that!

Had the same problem when calling rustup update on a separate row/RUN when building in docker. Including rustup update on the same row seemed to resolve the issue:

RUN curl --proto '=https' --tlsv1.2 -sSf curl https://sh.rustup.rs | sh -s -- -y && source $HOME/.cargo/env && rustup update
