arduino-builder

• Path: arch/maintained/arduino-builder
• Build failure during the 2026-07-07 “build all packages for x86_64” private-repo release pass (see repo_release_logs/maintained_arduino-builder.log).
• Source signature verification fails: arduino-builder-1.6.1.tar.xz ... FAILED (unknown public key 95FA6F43E21188C4) – this key isn’t in the build chroot’s/box’s GPG keyring. ERROR: One or more PGP signatures could not be verified! / Could not download sources.
• Same root cause as memory/arduino.md (same key ID) – see the note in memory/TOOLING_NOTES.md about missing validpgpkeys imports.
• Update 2026-07-07 later same day: imported the missing key (gpg --recv-keys 95FA6F43E21188C4, confirmed fine to do on the host for source-verification purposes specifically – see memory/feedback_no_host_installs.md) and retried. Got past signature verification, but hit a different, systemic-class failure: error: target not found: arduino-ctags – another custom package from this same tree (maintained/arduino-ctags, which itself built fine standalone earlier in this same pass), unresolvable by the chroot for the same intra-tree-dependency reason as memory/kdstatemachineeditor.md.
• Resolved 2026-07-07, same day, later still: built via the new scripts/archlinuxaba-x86_64-build chroot flavor (see memory/TOOLING_NOTES.md’s update), which adds our own private repo to the chroot’s pacman.conf – arduino-ctags resolved fine since it was already published. Built, signed, and published successfully.
