failed to determine state file: %w

Error message

failed to determine state file: %w

What it means

kubectxPrevCtxFile failed to determine the path of the state file that stores the previous context. It derives the path from the user's home/state directory; failure means HOME/XDG environment could not be resolved to a usable directory.

Solutions

1. Ensure the HOME environment variable is set to a valid directory
2. Alternatively set XDG_STATE_HOME (or XDG_CACHE_HOME depending on platform) to a writable path
3. Fix the environment in CI/containers where HOME is often missing
