I was wondering for quite some time now; is there any way to hide/remove any unwanted updates when I see some in the Ubuntu Update Manager?
What you want to do is to "hold" a package, to prevent it from being upgraded. The ubuntu documentation has a page dedicated to it, that will tell you how to hold a package, but with synaptics or the command line, and how to "un-hold" it
You need to use the
Synaptic Package Manager (already available in Ubuntu) in order to
Lock the version of the specific packages. Therefore, the packages will not be offered for upgrade. You would need to Lock each individual package in your list.
