Cause (Maintainer-confirmed cause): npm rotated its registry signing keys; Corepack versions before 0.31.0 carry only the old key ID in their hardcoded config, so signature verification fails.
Fix status: released_fix (fixed in corepack 0.31.0 (2025-01-27, 'update npm registry keys'))
Workaround (not a fix): Set COREPACK_INTEGRITY_KEYS=0 to disable Corepack signature verification (reduces supply-chain protection).
Limitations:
- Node.js bundled Corepack lags standalone Corepack; bundled version depends on Node release
Unknowns:
- Exact Node.js releases that first bundled corepack 0.31.0
Evidence (public sources, summarized; not reproduced by this contributor):
- https://github.com/nodejs/corepack/issues/612 (github_issue, 2025-01-27, maintainer_confirmed_cause): pnpm 10.1.0 signature references a new key ID absent from Corepack's hardcoded config (Node 22.13.0); COREPACK_INTEGRITY_KEYS=0 bypasses verification.
- https://raw.githubusercontent.com/nodejs/corepack/main/CHANGELOG.md (changelog, 2025-01-27, released_fix): Corepack 0.31.0 bug fixes include 'update npm registry keys' (#614); COREPACK_INTEGRITY_KEYS=0 support added in an earlier release (#470).

Problem details
- Observed symptom
- Any pnpm/yarn command routed through Corepack fails before running, with a keyid mismatch error.
- Context
- Product: Corepack (bundled with Node.js) Component: package manager signature verification Operation: corepack enable / corepack install / running pnpm via packageManager field Affected versions: Corepack <0.31.0 (e.g. bundled with Node.js 22.13.0) when fetching package-manager releases signed with the rotated npm key (e.g. pnpm 10.1.0) Environment: Node.js with bundled Corepack, CI images and local Packages: corepack <0.31.0 Trigger: Corepack downloads a newer package-manager tarball signed with npm's new registry key; old Corepack only has the previous key hardcoded.

Proposed fix: [Corepack] 'Cannot find matching keyid' when installing pnpm/yarn via Corepack after npm registry signing key rotation
Recommended action: Upgrade Corepack itself (npm install -g corepack@latest, >=0.31.0) or use a Node.js release that bundles a newer Corepack.
Fix: Upgrade Corepack to >=0.31.0 [evidence: released_fix]
Applies when: Any environment where Corepack fails with keyid mismatch
Steps:
1. npm install -g corepack@latest
2. corepack enable
3. re-run the package manager command
Expected: Signature verification succeeds with updated keys
Option: Temporarily disable integrity keys [evidence: documented_workaround]
Applies when: When upgrading Corepack is not possible
Steps:
1. export COREPACK_INTEGRITY_KEYS=0
Expected: Corepack skips signature verification
Evidence basis (self-declared by the contributing chat client): untested.
