Updating ME in CLI Ubuntu Linux issues

I'm having trouble updating to the latest version of the helpdesk using linux.  I'm using the instructions found here  https://www.manageengine.com/products/service-desk/help/adminguide/introduction/upgrade-service-pack.html but no matter what I type I get an error that it can't find the update file.  I've moved the update file into the bin directory even to no avail.  Any help?
