Charmcraft fails to launch LXD instance with high uid (`raw.idmap=both 595156457 0`)
Metadata
Current evaluation
High host UID causes LXD launch failure via raw.idmap=both; diagnosed as craft-providers idmap issue, fixed upstream by separate uid/gid maps and charmcraft now depends on fixed version.
Suggested action: close resolved
Reason: Maintainer mr-cal identified the raw.idmap line and opened canonical/craft-providers#259; that issue was resolved by merged PR canonical/craft-providers#780, which sets uid and gid maps separately. Charmcraft's pyproject.toml now requires craft-providers>=3.7.1, so the fix is included in current dependencies.

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?

| Issue | Project | State | Summary | Similarity |
|---|---|---|---|---|
| #1260 Charmcraft hangs or fails with LXD 5.18 | charmcraft | closed | LXD released a fix for the 5.18 image lookup failure; Charmcraft’s separate edge retry hang was fixed by craft-providers#415 (commit da95d03). | |
| #259 Cannot launch lxd instance with high uids | craft-providers | open | LXD launches failed for host UIDs above 65,535; commit 5717e2c and PR #780 now configure separate UID and GID raw.idmap entries, resolving the reported failure. | |
| #92 Suddenly getting charmcraft internal error with charmcraft pack | craft-providers | closed | Resolved upstream in LXD 4.23 revision 22525+, which corrected overly strict device-name validation; `snap revert lxd` was a temporary workaround. | |
| #646 Failed to inject host Charmcraft snap into target environment | charmcraft | closed | Report of charmcraft 1.4.0 failing to inject the host snap into the LXD build env. Closed without a code fix: a user fixed it with `charmcraft clean --verbose` and lengau closed it in Jan 2024 as not reproducible on current versions. | |
| #769 LXD idmap improperly set for high uids and gids | craft-providers | closed | Fixed by merged PR #98 (76a2d3a): LXD raw.idmap now maps the host UID and GID separately, correcting ownership for high, mismatched IDs. |
