The installer did not report the destination path.

Error message

The installer did not report the destination path.

What it means

rollback_hash_mismatch runs when a plugin install fails its post-install hash verification: it uninstalls the just-written plugin by taking the parent directory of the destination path the installer reported. If the installer never reported a destination (installed_path is None), the rollback cannot locate the plugins directory and fails with this localized message; the hash-mismatch outcome is then reported without automatic cleanup.

Solutions

1. List the plugins directory / plugin registry and remove the partially installed plugin by hand.
2. Re-run the plugin install to get a clean, verified state.
3. Check disk space and network stability if the install was interrupted.
4. Report as a bug with logs - the installer must always report its destination for rollback to work.

// Rust: after install, confirm a destination was reported before trusting rollback
let installed = install_plugin(name)?;
anyhow::ensure!(
    installed.path.is_some(),
    "installer reported no destination; automatic rollback unavailable"
);

// Rust: manual cleanup fallback when rollback lacks a path
Err(err) if err.to_string().contains("did not report the destination path") => {
    manual_plugin_cleanup(name).await?; // remove by hand from the plugins dir
    Err(err.context("hash mismatch; plugin removed manually"))
}

When it happens

Trigger: The plugin install pipeline aborts before recording its extraction path (early IO failure, interrupted download, Ctrl-C mid-extract) and the hash check then finds a mismatch; a partial install leaves files behind with no path metadata; an invariant break between installer stages.

Common situations: Interrupted plugin installs (disk full, network drop); corrupted downloads failing hash; version skew between installer stages.
