Current evaluation

Reporter's kicad-dev-snap failed on Launchpad (Xenial) with linker error 'cannot find -lngspice' while building locally succeeded. 10 years old, zero comments, no maintainer response, Xenial base long EOL.

Suggested action: close stale

Reason: The issue is 3658 days old with 0 comments and no maintainer engagement, and it targets a Xenial-based Launchpad build of a third-party snap (kicad-dev-snap) — that base is no longer supported and the current snapcraft is a fully rewritten codebase, so the report is no longer applicable. It is also effectively a support question about the reporter's own snapcraft.yaml (missing library path for -lngspice), not a snapcraft defect.

Impact: 10 Quick Win: 8.0 Staleness: 100 Complexity: 20 Confidence: 80 Support Request: 85

Issue body

I have the error of building snap in LP: https://launchpadlibrarian.net/280787471/buildlog_snap_ubuntu_xenial_amd64_kicad-dev-snap_BUILDING.txt.gz Error message: /usr/bin/ld: cannot find -lngspice collect2: error: ld returned 1 exit status Ngspice built OK (see log). When I was making snap in the local machine all was OK. Snap src: https://code.launchpad.net/~eldar/kicad/+git/kicad-dev-snap Snap pkg: https://code.launchpad.net/~eldar/+snap/kicad-dev-snap
