Upgrading from 5.7.3.1 to 5.7.4.2 - Error

Permalink December 10, 2015 at 4:46 PM

I am updating a site that was built in v5.7.2 and have successfully upgraded to 5.7.3.1.

When I try to the do the next step to 5.7.4.2 I get the following error message

Symfony\Component\ClassLoader\MapClassLoader::loadClass(): Failed opening required '/Applications/MAMP/htdocs/clan-line.org.uk/packages/list_files_from_set/controller.php' (include_path='/Applications/MAMP/htdocs/clan-line.org.uk/updates/concrete5.7.4.2_remote_updater/concrete/vendor:.:/Applications/MAMP/bin/php/php5.6.2/lib/php')

Now, I am really confused as I do not have a package with that name in the build. Does anyone know why this is happening please and what I can do to rectify it?

Thanks
