Current evaluation

Snapcraft bug (2017): with two remote parts, a file staged by the xwayland-kiosk-helper remote part (lib/libxwayland-preload.so) is not copied into prime, while another file from the same part is. No maintainer response or activity in 8+ years.

Suggested action: close stale

Reason: The issue is 3035 days (~8.3 years) old with 0 comments, no labels, and no maintainer interaction, and it predates the current snapcraft parts architecture, so the reported stage-to-prime behavior for remote parts is very likely no longer applicable to a supported version. I could not directly verify the current remote-parts code (repo tooling returned 'No pinned SHA available'), which is why confidence is held moderate rather than high.

Impact: 35 Quick Win: 15.75 Staleness: 95 Complexity: 55 Confidence: 55 Support Request: 25

Issue body

I'm trying to use 2 remote parts simultaneously in this simplified YAML: name: dual-remote-parts-bug version: 0.1 summary: Bug description: Bug confinement: strict grade: devel apps: dual-remote-parts-bug: command: ls $SNAP/lib parts: bug: plugin: nil after: [desktop-gtk2, xwayland-kiosk-helper] The second remote part "xwayland-kiosk-helper" is defined here: https://github.com/gerboland/xwayland-kiosk-helper/ It creates a file lib/libxwayland-preload.so which I see is created in the "stage" directory, but it is not copied into the "prime" directory for some reason. But the bin/xwayland-kiosk-launch file is copied?! There is no "prime" specification in the remote snap, so shouldn't everything that is staged be copied into the prime?
