How can I update the stable toolchain when I get the error "some components unavailable for target i386-apple-ios/armv7s-apple-ios"?

I try to run

rustup update stable

and I get the following output.

info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'
info: latest update on 2020-05-07, rust version 1.43.1 (8d69840ab 2020-05-04)
error: some components unavailable for download for channel stable: 'rust-std' for target 'i386-apple-ios', 'rust-std' for target 'armv7s-apple-ios', 'rust-std' for target 'armv7-apple-ios'
If you require these components, please install and use the latest successful build version,
which you can find at <https://rust-lang.github.io/rustup-components-history>.

After determining the correct date, install it with a command such as:

    rustup toolchain install nightly-2018-12-27

Then you can use the toolchain with commands such as:

    cargo +nightly-2018-12-27 build

While I can install the latest stable toolchain using

rustup toolchain install stable-2020-05-07

That creates a separate toolchain.

rustup toolchain list
stable-2020-05-07-x86_64-unknown-linux-gnu (default)
stable-x86_64-unknown-linux-gnu
nightly-2020-05-07-x86_64-unknown-linux-gnu

I can use this new toolchain as the default (as I am now), but it's going to be a pain moving forward as I can't just use rustup update.

Running rustup toolchain install stable yields the same error.

How can I get the stable Rust toolchain to update via rustup update run?

The Rust team regrets to announce that Rust 1.41.0 (to be released on January 30th, 2020) will be the last release with the current level of support for 32-bit Apple targets. Starting from Rust 1.42.0, those targets will be demoted to Tier 3.

Reducing support for 32-bit Apple targets

You will need to remove those components using rustup component remove. I can't test the exact invocation, but something like:

rustup component remove --toolchain stable --target i386-apple-ios rust-std
rustup component remove --toolchain stable --target armv7s-apple-ios rust-std
rustup component remove --toolchain stable --target armv7-apple-ios rust-std

Once removed, you can update your compiler.
