Security Patch SUPEE-8788 failing at downloader/Maged/View.php (M1 v1.5.1.0) [duplicate]

Question

On magento v1.5.1.0 patch Supee 8788 fails at downloader/Maged/View.php

I downloaded a fresh install of Magento v1.5.1.0, copied the downloader file over and retried but still fails with the same error:

patching file downloader/Maged/View.php
Hunk #1 FAILED at 154.
1 out of 1 hunk FAILED -- saving rejects to file downloader/Maged/View.php.rej

Answer 1

To fix this:

Download the latest version of Magento (currently v1.9.3.0) and replace the downloader/Maged/View.php file with the one from the latest release.

Then remove this function (around line: 156):

/**
   * Retrieve Session Form Key
   *
   * @return string
   */
  public function getFormKey()
  {
      return $this->controller()->getFormKey();
  }

Run the patch install again and the patch will be applied successfully.
