info: profile set to 'default'
info: syncing channel updates for 'stable-armv7-unknown-linux-gnueabihf'
info: latest update on 2019-09-26, rust version 1.38.0 (625451e37 2019-09-23)
error: some components unavailable for download for channel stable: 'clippy', 'rustfmt'
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

clippy and rustfmt are not available for the latest nightly at the moment you tried to update. you can remove them first or wait a few days.

I see, but i just install it first time in my new raspberry pi4.

just run:
curl https://sh.rustup.rs -sSf | sh

Thanks for your help.

You can try to choose custom installation and then enter nightly-2019-10-13 as default toolchain. That is the latest nightly with rustfmt and clippy available.

Edit: You could try to set the profile to minimal after choosing custom installation. That will prevent installation of clippy and rustfmt.

I'm surprised you're getting this error for a stable install.

6

Any idea why clippy and rustfmt couldn't sync with rustc releases? Those errors are annoying.

On most targets the clippy and rustfmt are available on both stable and beta, but I think this is not the case for so called tier 2 targets.

Quoting https://forge.rust-lang.org/release/platform-support.html:

Tier 2 platforms can be thought of as "guaranteed to build". Automated tests are not run so it's not guaranteed to produce a working build, but platforms often work to quite a good degree and patches are always welcome!

@bjorn3 That makes sense. I think the error message from rustup is too nightly-centric though.
