A core24 snap creation fails on compression (RISCV64)
Metadata
Current evaluation
core24 riscv64 snap builds failed at `snap pack` (exit 20). Maintainers traced it to older snapd on RISCV lacking core24 support, not snapcraft; fixed once newer snapd shipped. Reporter confirmed 'Fixed now' on 2024-10-26.
Resolution: closed not a bug
Reason: ~the-meulengracht identified the failure as a known upstream snapd issue on RISCV (stable snapd too old for core24 riscv), not a snapcraft defect, and the reporter confirmed 'Fixed now' on 2024-10-26 after snapd updated, with core22 as an interim workaround. No snapcraft code change was made.

Issue body
Since July, the “final” step (compression) of creating a snap package is failing, printing the message below:
```
[...]
Running linter: library
Creating snap package...
Command '['snap', 'pack', '--filename', 'john-the-ripper_1.9J1+07aef97_riscv64.snap', '--compression', 'xz', PosixPath('/build/john-the-ripper/prime'), PosixPath('/build/john-the-ripper')]' returned non-zero exit status 20.
Full execution log: '/root/.local/state/snapcraft/log/snapcraft-20240914-141157.452959.log'
[...]
```
It works on all other archs and the message seems to blame the compression process itself. In other words, it's not related to “my code”.
