Snapcraft snap broken on trusty
Metadata
Current evaluation
Snapcraft 2.39.2 snap failed on Trusty: mksquashfs couldn't find liblz4.so.1 because ELF rpaths weren't set. Fixed by snapcore/snapcraft#1988 (commit 17f1f8c2f), which only sets rpaths to libs of the same arch; verified via edge/1752964-fix-trusty channel.
Resolution: closed resolved
Reason: Maintainer kyrofa identified that rpaths weren't being set for mksquashfs and shipped a fix in snapcore/snapcraft#1988 (commit 17f1f8c2f, 'elf: only set rpaths to libs of the same arch'), which was validated by a reporter on the edge/1752964-fix-trusty channel before the bug was closed.

| stealth/space-bunny-alpha | — | closed stale | Closed without a recorded fix: Snapcraft 2.39.2's snap failed on Trusty because mksquashfs could not load liblz4.so.1; LP #1752964 has no comments or resolution. | |
| qwen/qwen3.6-35b-a3b | — | — | Closed without resolution. Snapcraft v2.39.2 failed on Ubuntu Trusty due to a missing liblz4.so.1 dependency for mksquashfs. No comments were posted, and the report was likely abandoned following Trusty's end-of-life. | |
