I try to auto upgrade from 3.5.1 to 3.6.0 and get the message 'The archive file is corrupt, truncated or archive parts are missing"

If I try to Install from URL my message is "Unable to find install package"

If I try to upload the package manually the loader runs for a while and then terminates with no upload nor any message

/logs and /tmp exist and are correctly set in global config

thanks for any insight- Nikos

    Can you verify that your hosting account has enough room for the uploaded file and that the file type (typically zip) is allowed? Sep 1, 2016 at 13:15

For others that may reach here with similar issue for recent Joomla updates (e.g. 3.6.5).

In the case you get this error message, it usually means what it says: That the update package that was transferred to your Joomla instance's tmp folder is indeed corrupted. A corrupted file may occur for various reasons - no need to analyze this here.

If this happens, any new effort to initiate the update procedure through the Joomla Update Component will end with the same result - as Joomla will keep finding the corrupted zip file in the tmp folder and will try to use this for the update.

So the solution here is to connect with FTP to your site and go into the tmp folder of your Joomla and delete the previous downloaded update package. This will force the Joomla Update Component to fetch and download a new zip archive for updating your Joomla site - hopefully this time the archive will be transferred at full and with no corruption.

  • it is worth mentioning that the temp folder in this case is the one in administratorfolder. Jul 21, 2017 at 8:02
  • The strange thing is that i am still getting the same error message even when the temp folders are empty. and after getting that message, the temp folders are still empty, nothing downloaded there. I have double checked the my temp folders in joomla and in configuration.php. I have no idea why this is happening. Jul 21, 2017 at 8:09

Did you update the "joomla update component" (sorry it may not be the exact wording, I've got a french installation) before updating to 3.6.0 ? I guess you don't do it (?)
