arduino

• Path: arch/maintained/arduino
• Build failure during the 2026-07-07 “build all packages for x86_64” private-repo release pass (see repo_release_logs/maintained_arduino.log).
• Source signature verification fails on multiple bundled sources (libastylej-2.05.1-5.zip, liblistSerials-1.4.2-2.zip, etc.): unknown public key 95FA6F43E21188C4. Same key ID as memory/arduino-builder.md – this GPG key just isn’t present in the build box’s keyring, so any package validating against it will fail identically no matter what else is true about the package.
• Update 2026-07-07 later same day: imported the missing key (gpg --recv-keys 95FA6F43E21188C4, fine to do on the host for source-verification purposes – see memory/feedback_no_host_installs.md) and retried. Got past signature verification, but hit intra-tree dependency resolution next: error: target not found: arduino-builder (custom package from this tree, same class as memory/kdstatemachineeditor.md) plus possibly-also-missing java-runtime=8 (not checked further – masked by the arduino-builder failure in the same transaction). Not fixed further as part of this pass.
