@AnwarShah While I don't think questions that are just about how to use Ubuntu to fix Windows are off-topic, this question seems mostly about what operations would have to be performed to fix it, rather than how to perform them in Ubuntu. It's not as though the OP has posted a Windows procedure and asked how to do the same thing in Ubuntu. So I agree--IMO we should close this as off-topic. 3 more close-votes needed.
@AnwarShah Yes. I mean, you don't have to remove them one by one in the sense of issuing a separate removal command for each (you can do sudo apt-get remove package1 package2 ... or select multiple packages in Synaptic for removal), but yes, removing the metapackage doesn't remove the dependencies.
If none of them depend on anything else that is installed, including anything installed after the metapackage was installed, then removing the metapackage and running sudo apt-get autoremove will remove them. But it's quite common that other GNOME related packages will be installed later that also specify some of the gnome-core dependencies as their dependencies.
@AnwarShah If nothing else depends on it, then sudo apt-get autoremove (issued after removing the metapackage) should remove its dependencies (unless they were marked as manually installed).
the difference would be that the paid version would contain things you wouldn't get in the free version, like previews, extra details, and even extended versions
@AnwarShah Regarding the question about removing all of gnome-core's dependencies: Since you have the command apt-cache depends gnome-core | cut -f 2 -d ':' | tr '\n' ' ' that lists them all, delimited by whitespace, you can use the command sudo apt-get remove $(apt-cache depends gnome-core | cut -f 2 -d ':' | tr '\n' ' ') to remove them all.
@EliahKagan Thanks for the tip. But I did not provide that because, in the output there will be some virtual packages with <package-name> which must be manually removed from the command.

I am writing a small application using PyGI which will interactively draw a line on a Gtk.DrawingArea between mouse clicks. But I am unable to figure out how to draw using the cairo context at the coordinates returned by the mouse click event.

BTW a hacky way to update your Precise/Quantal is to setup a chroot on the ajaxterm server, and upload your dpkg stuff to it, then do an apt-get download to get all the debs, download them to your computer and dpkg -i *
