Hello what is the manual steps for macos? can you please provide the exact steps?, i am having the same issue

Whenever installing/updating/re-installing, getting this error every time:

Can you try installing a different Xtensa Rust version? espup update -v 1.83.0.1 and see if the issue still appear

espup update --nightly-version 1.84.0,
The nightly version arg is for installing a 1.84.0 nightly channel (used for Riscv devices, not for Xtensa devices)

I'm also on macOS, had the same issue where espup install would fail with "Error: failed to iterate over archive", and with v1.83.0.1 it did install the toolchain.

[liebman]

I think the issue is that for some reason there is not apple x86_64 build of the rust compiler....

[MabezDev]

For some reason the build didn't trigger - I might have skipped over it by accident.

I've started the build now: https://github.com/esp-rs/rust-build/actions/runs/12896349203 hopfully that will go green in the next few hours and things will be resolved. Sorry about that!

[SergioGasquez]

Can we confirm that the issue is now resolved? @0x53A @zpg6

I think we should improve the error message as its quite misleading that the download does not fail and the error is failed to iterate over archive

espup update --nightly-version 1.84.0

It passes that step:

[info]: Installing Xtensa Rust 1.84.0.0 toolchain
[info]: All downloads complete
[info]: All downloads complete
[info]: Installing 'rust' component for Xtensa Rust toolchain
[info]: Installing 'rust-src' component for Xtensa Rust toolchain
[info]: Update successfully completed!

But when I verify:

. $HOME/export-esp.sh
rustc --version

I get:

rustc 1.83.0 (90b35a623 2024-11-26)

If I try 1.83.0.1:

espup update -v 1.83.0.1

It seems to pass as well:

[info]: Installing Xtensa Rust 1.83.0.1 toolchain
[info]: All downloads complete
[info]: All downloads complete
[info]: Installing 'rust' component for Xtensa Rust toolchain
[info]: Installing 'rust-src' component for Xtensa Rust toolchain
[info]: Update successfully completed!

I still am at 1.83.0

(Open new terminal)

. $HOME/export-esp.sh
rustc --version

Returns:

rustc 1.83.0 (90b35a623 2024-11-26)

The issue seems to be resolved. Can close this Bug.

It sounds a bit like the http error code is not checked. That is, github returns a 404, but espup ignores that and just writes a zero-length file, which then can’t be extracted.

Claude told me it would replace this block:

espup/src/toolchain/mod.rs

Lines 121 to 124 in 54b453b

	let resp = {
	let client = build_proxy_async_client()?;
	client.get(&url).send().await?
	};

with this:

let resp = {
    let client = build_proxy_async_client()?;
    let resp = client.get(&url).send().await?;
    if !resp.status().is_success() {
        return Err(Error::HttpError(resp.status().to_string()));
    }
    resp
};
