Incorrect toolchain check when running cross with active or default toolchain

Describe your issue

When running any cross command, cross tries to download the stable version while it is already installed.

This is because when running rustup toolchain list, my toolchain stable has a suffix (active, default), which makes the check fail. I believe adding the --quiet flag at the end of the command should fix the issue.

I have tried both the latest stable 0.2.5 version and the lastet version on the main branch (9e2298e at the time of writing)

Two months ago, on a version not released yet, the command rustup toolchain list was replaced with rustup --quiet toolchain list. This however does not fix the issue as the --quiet flag applies to the rustup command and not the list command.

What target(s) are you cross-compiling for?

@Rileran can you try #1681 to see if it fixes your problem?

[Rileran]

@reneleonhardt This fix works for me, thanks!

Hey! I'm seeing issues that may be related to this fix? I build cargo-cross from git.

Thank you for the report!
Could you please add new commands before the failing one and rebuild it?

rustup --version # rustup 1.28.2 (2025-04-28)
rustup toolchain list --help

Hi,

I also encountered an error with rustup v1.26.0 (ubuntu noble 1.26.0-5build1).
FYI: Rustup is installed with APT.

$ cross build --release --target aarch64-unknown-linux-musl
Error: 
   0: `rustup toolchain list --quiet` failed with exit status: 1

Location:
   src/errors.rs:147

Stdout:
   error: Found argument '--quiet' which wasn't expected, or isn't valid in this context

        If you tried to supply `--quiet` as a value rather than a flag, use `-- --quiet`

   USAGE:
       rustup toolchain list [OPTIONS]

   For more information try --help
$ rustup --version
rustup 1.26.0 (2024-04-01)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.87.0 (17067e9ac 2025-05-09)`
$ rustup self update
error: self-update is disabled for this build of rustup
error: you should probably use your system package manager to update rustup

Of course, this error should be fixed after installing rustup by non-APT methods.
