could not rename/copy file from %q to %q: %w

Error message

could not rename/copy file from %q to %q: %w

What it means

moveFiles calls renameOrCopy for each resolved move and the rename (with cross-device copy fallback) failed for one from→to pair. The wrapped error is the underlying os.Rename or copyTree failure.

Solutions

  1. Inspect the wrapped error for the OS-level cause (permission, ENOSPC, missing file)
  2. Fix permissions or free disk space on the destination filesystem
  3. Clean the plugin's install directory and re-run the install
  4. If the source vanished (race), re-extract the archive / re-download and retry
Defensive patterns

Strategy: retry

Validate before calling

for _, m := range moves {
    if _, err := os.Lstat(m.from); err != nil { return fmt.Errorf("source vanished: %w", err) }
}

Try / catch

if err := moveToInstallDir(...); err != nil && strings.Contains(err.Error(), "rename/copy file") {
    // fix perms/space, remove partial install, retry install command once
}

Prevention

When it happens

Trigger: A per-file move failing: destination exists and cannot be removed, permission error on source or destination, cross-device rename where the copyTree fallback also fails (e.g. unreadable source file, disk full).

Common situations: Partial previous install left root-owned files; antivirus/locking on Windows; /tmp on a different device with the fallback copy hitting a full disk; file removed between glob and rename.
