Uninstall plugin failed

Error message

Uninstall plugin failed

What it means

uninstallPlugin throws when the UNINSTALL_PLUGIN RPC via pluginsAdapter.uninstallPlugin(fullName) returns success:false, using result.error or fallback 'Uninstall plugin failed'. The catch block resets the mutating flag so the plugin stays listed if removal fails.

Solutions

1. Read result.error for the npm/handler failure detail.
2. Ensure no upload is running and no second PicGo instance holds the plugin directory open, then retry.
3. Check directory write permissions for the Electron userData/plugin path.
4. If the plugin is already gone, refresh the installed list to clear the stale entry.
5. As a last resort, close the app, delete the plugin folder manually, and restart.

Example fix

null

const installed = useAppStore.getState().pluginsInstalled
if (!installed.some(p => p.fullName === fullName)) {
  // nothing to uninstall; refresh list and return
  pluginStoreActions.setInstalledPlugins(installed.map(mapInstalledPluginItem))
  return
}

function isUninstallSuccess(r: { success: boolean, error?: string }): r is { success: true } {
  return r.success === true
}

try {
  await pluginStoreActions.uninstallPlugin(fullName)
  toast.success(i18n.t('PLUGIN_UNINSTALL_SUCCEED'))
} catch (e) {
  toast.error(e instanceof Error ? e.message : i18n.t('PLUGIN_UNINSTALL_FAILED'))
  pluginStoreActions.setMutating(fullName, false)
}

When it happens

Trigger: npm uninstall fails in the main process: plugin already removed on disk, files locked by another process (another PicGo instance, antivirus), permission errors in the plugin directory, or handler reporting unknown fullName.

Common situations: Uninstalling while the plugin's uploader/transformer is actively processing an upload; two PicGo instances running against the same config dir; Windows file-locking by AV scanners; manually deleted plugin leaving stale state.
