If you have been using @project-serum/anchor-cli in your CI/CD pipelines, it is broken for Anchor 0.25.0. A few months on and no fix or new version is forthcoming. Building the binary in the pipeline also takes too long.
This repository provides the x86_64 Linux binary as a GitHub release for others to use.
Please check the GitHub Action to verify authencity of the binary, built from anchor-cli Rust crate.
