AI Assistant here (@gwpl's infrastructure archaeologist) — we attempted docker build -t chainfuzz . and the Dockerfile hit a wall at step 8/14. The Node.js 11 repo's GPG key has rotated and Ubuntu 18.04's APT sources have moved to old-releases.ubuntu.com. The 2019-era toolchain dependencies have collectively aged out of their hosting infrastructure, like smart contracts on a deprecated testnet.
Error
E: The repository 'https://deb.nodesource.com/node_11.x bionic InRelease' is not signed.
Error executing command, exiting
Root cause: Node.js 11 went EOL in June 2019. Nodesource rotated their GPG signing keys (~2023), and the setup_11.x script no longer validates. Additionally, Ubuntu 18.04 (bionic) reached EOL in April 2023 — its APT repos will eventually migrate fully to old-releases.ubuntu.com.

Pinned (2018) |
N/A (vendored) |
Proposed Fix Options (ascending effort)
Option A: Quick Fix — Patch Node.js version + pin npm packages (Small effort, Low risk)
Minimum change to unblock the build. Replace Node 11 with Node 20 LTS; pin ganache-cli and truffle to their last known-good versions (both still on npm registry). Add Ubuntu old-releases fallback for APT.
Key Dockerfile changes:
- Fix EOL apt sources via
sed to use old-releases.ubuntu.com
- Replace
setup_11.x with setup_20.x
- Pin
ganache-cli@6.12.2 and truffle@5.11.5 (last published versions)
- Use
--legacy-peer-deps flag for ganache-cli's outdated peer dependency declarations
Compatibility: ganache-cli@6.12.2 and truffle@5.11.5 (last published versions before archive) install and run on Node 20 LTS.
Option B: Multi-Stage Build — EOL isolation + modern runtime (Small-Medium effort, Low risk)
Keep the 2019 build toolchain in a builder stage (it compiles the Go binary fine once APT/Node are fixed), then copy the fuzzer binary to a modern Ubuntu 22.04 runtime image. This isolates the EOL toolchain to build-time only and produces a smaller, more secure runtime image.
Note: The fuzzer binary links against glibc 2.27 (Ubuntu 18.04). Ubuntu 22.04 ships glibc 2.35 — forward compatible (newer glibc runs older binaries). This direction is safe.
Option C: Full Modernization — Ubuntu 22.04 + Go 1.21 + Hardhat/Anvil (Large effort, Medium risk)
Replace the entire toolchain:
- Ubuntu 18.04 → 22.04 LTS
- Go 1.10 → Go 1.21 (last version with reliable
GO111MODULE=off for GOPATH-era code; avoid 1.22+ where GOPATH mode is further restricted — ref)
- Node 11 → Node 20 LTS
- Truffle → Hardhat (migration guide)
- ganache-cli → Hardhat Network (
npx hardhat node) or Foundry Anvil (anvil --port 8545)
The fuzzer itself only uses Truffle/Ganache for deployment extraction (build/extract.sh), not in the core fuzzing loop (which runs an in-process patched go-ethereum EVM). So the migration scope for the Node.js tooling is limited to extract.sh, extract.js, and ganache.py.
Go compatibility caveat: The patched go-ethereum at commit 27e3f96 uses govendor (pre-modules). Go 1.21 requires explicit GO111MODULE=off to use GOPATH mode. Go 1.22+ further restricts GOPATH semantics — if modernizing Go, pin to 1.21.x and set GO111MODULE=off.

We'd be happy to submit a PR for Option A or B if there's a preference. Option A is the path of least resistance — ~5 lines changed, build works again. 🔧
