Charmcraft fails to launch LXD instance with high uid (`raw.idmap=both 595156457 0`)
Metadata
Current evaluation
Charmcraft pack fails to launch LXD instance when host UID is very high (e.g. 595156457) due to raw.idmap subid conflict. Root cause identified in craft-providers; workaround found via forum post; reporter confirmed resolved. Real fix tracked in craft-providers#259 (open).
Suggested action: close not a bug
Reason: The bug is in craft-providers (a dependency), not charmcraft itself, and is properly tracked in canonical/craft-providers#259. The reporter confirmed the forum-post workaround 'entirely solves my problem,' and mr-cal noted the issue was left open only so others could find that workaround. With 381 days of inactivity and the real fix tracked upstream, this charmcraft issue is a duplicate of craft-providers#259 and can be closed with a pointer to the workaround and upstream issue.

Launching lxd by hand works just fine:
```bash
$ lxc launch ubuntu:22.04 u2
Creating u2
Starting u2
```
Something tells me `'raw.idmap=both 595156457 0'` is causing havoc here.
How can I investigate this further?

| #497 charmcraft Pack is not Working | charmcraft | closed | Resolved via user environment fix. The permission error stemmed from running charmcraft as root with root-owned files. Switching to a regular user, adding them to the lxd group, and correcting ownership allowed pack to succeed. No code changes required. | |
| #1260 Charmcraft hangs or fails with LXD 5.18 | charmcraft | closed | Closed due to an upstream LXD bug. A fix was released for LXD 5.18 compatibility, resolving the hangs and failures. The investigation also uncovered a separate craft-providers issue tracked independently. |
