#22036 "Build wheels" jobs failing on Linux GitHub runners Issue created by tdyas The "build wheels" jobs are failing on Linux due to

rustup

refusing to install the applicable Rust toolchain. The error results later when the CI tries to build the Rust code and no Rust toolchain is installed. The error which ends the job is in the Build Wheels step. But the Rust toolchain is missing because it was not installed during the previous rustup step and the CI job did not verify installation and fail at that point. Rustup no longer installs the toolchain: https://blog.rust-lang.org/2025/03/02/Rustup-1.28.0.html pantsbuild/pants
