# error: failed to run maintenance: could not create temporary file: Permission denied

- **ID:** `git/error-failed-to-run-maintenance`
- **Domain:** git
- **Category:** system_error
- **Error Code:** `EACCES`
- **Verification:** ai_generated
- **Fix Rate:** 85%

## Root Cause

Git's background maintenance tasks (like gc or commit-graph write) cannot create temporary files in the repository's object directory due to insufficient filesystem permissions or disk space.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| git 2.31.0 | active | — | — |
| git 2.40.0 | active | — | — |
| git 2.44.0 | active | — | — |

## Workarounds

1. **chmod -R u+w .git/objects  # Grant write permission to the objects directory for the current user** (85% success)
   ```
   chmod -R u+w .git/objects  # Grant write permission to the objects directory for the current user
   ```
2. **df -h && du -sh .git  # Check disk space; if full, free up space by removing large files or running git maintenance stop to disable auto-maintenance** (75% success)
   ```
   df -h && du -sh .git  # Check disk space; if full, free up space by removing large files or running git maintenance stop to disable auto-maintenance
   ```

## Dead Ends

- **** — Running git gc manually without addressing permission issues will fail with the same error because gc also needs to create temp files. (95% fail)
- **** — Changing ownership of .git/objects to root with chown -R root:root can break other git operations and is not a proper fix. (80% fail)
