writing config file: %w

Error message

writing config file: %w

What it means

Fires in WriteFullConfig when os.WriteFile fails to persist the marshalled global config back to the config file (default ~/.skaffold/config). Typically a filesystem-level failure: permissions, read-only home, disk full, or the file being locked.

Solutions

1. Check write permissions on the config file and its directory: ls -l ~/.skaffold/config
2. Free disk space or remount the filesystem read-write if applicable
3. Remove or fix a corrupted/locked config file so skaffold can rewrite it
