Joomla: An error message occurred after uploading a package
Check the following things:
Make sure your folder for temporary files is correct and writable (Joomla global configuration)
Make sure the target folders are writable (e.g. components, modules, plugins/*, administrator/components)
Make sure your webserver allows upload of files larger than 32MB (see php.ini settings post_max_size and upload_max_filesize). Check the size of your update package and make sure both settings are high enough
Make sure that the PHP.ini setting max_execution time is at least 90 seconds
Check for any warnings on the Joomla extension manager page.
