🛑 Build Failed: Compilation

undefined: cryptoutils.ValidatePubKey

Build Details

Category	Details
Build System	Go
Failure Point	go build command during compilation of github.com/sigstore/cosign/v2/pkg/cosign package

Root Cause Analysis 🔍

The code is referencing cryptoutils.ValidatePubKey function which is not defined or not accessible, likely due to a dependency version mismatch or API changes in the cryptoutils package. This appears to be caused by incompatible versions between the cosign v2.6.0 dependency and the cryptoutils library after the go/bump step updated dependencies.

Analysis

No similar build failures were provided for analysis. However, the error "undefined: cryptoutils.ValidatePubKey" indicates a Go compilation issue where a function from the cryptoutils package is not accessible. This typically occurs when: 1) The function has been removed or renamed in a newer version of the dependency, 2) The import path has changed, or 3) There's a version mismatch between dependencies. Given that the failure occurred after a go/bump step that updated golang.org/x/[email protected] and github.com/sigstore/[email protected], this suggests an incompatibility between the updated dependencies and the cosign v2.6.0 dependency.

Explanation

The build failure occurs because the code references cryptoutils.ValidatePubKey which is not defined, likely due to API changes in the sigstore ecosystem. The go/bump step updated golang.org/x/crypto and github.com/sigstore/fulcio but did not update the cosign dependency, creating a version mismatch. The ValidatePubKey function may have been moved, renamed, or its signature changed in newer versions of the cosign/cryptoutils libraries. By explicitly bumping github.com/sigstore/cosign/v2 to a more recent version (v2.8.0), we ensure that the codebase has access to the correct API definitions that are compatible with the updated crypto and fulcio dependencies. This approach maintains consistency across the sigstore ecosystem dependencies.

Alternative Approaches

• Pin all sigstore-related dependencies to specific compatible versions that are known to work together
• Remove the go/bump step entirely and rely on the upstream go.mod dependency versions
• Update only the golang.org/x/crypto dependency without updating fulcio to avoid cascade compatibility issues
• Add a replace directive in go.mod to use a specific fork or version of the problematic dependency
