# fatal: Failed to recurse into submodule path 'subdir/submodule'

- **ID:** `git/submodule-checkout-failed`
- **Domain:** git
- **Category:** runtime_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

Git cannot checkout or update a submodule due to issues such as missing submodule URL, network failure, or local changes in the submodule.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 2.39.0 | active | — | — |
| 2.40.0 | active | — | — |
| 2.41.0 | active | — | — |

## Workarounds

1. **Check the submodule URL in .gitmodules and verify network access: 'git config --file .gitmodules submodule.subdir/submodule.url'. Then run 'git submodule sync' and 'git submodule update --init --recursive'.** (85% success)
   ```
   Check the submodule URL in .gitmodules and verify network access: 'git config --file .gitmodules submodule.subdir/submodule.url'. Then run 'git submodule sync' and 'git submodule update --init --recursive'.
   ```
2. **If the submodule has local changes, stash or commit them first: 'cd subdir/submodule && git stash && cd ../.. && git submodule update --init --recursive'.** (90% success)
   ```
   If the submodule has local changes, stash or commit them first: 'cd subdir/submodule && git stash && cd ../.. && git submodule update --init --recursive'.
   ```

## Dead Ends

- **Running 'git submodule update --init --recursive' multiple times without checking the submodule URL.** — If the submodule URL is wrong or inaccessible, repeating the command won't fix the underlying issue. (70% fail)
- **Deleting the submodule directory and re-running 'git submodule update'.** — This may work if the submodule was corrupted, but it doesn't address URL or network issues. (40% fail)
- **Manually editing .gitmodules without understanding the submodule dependency.** — Incorrect changes to .gitmodules can break the submodule setup further. (60% fail)
