However, the following software will be uninstalled due to dependency after being uninstalled:

Virtualbox

If you want to retain some software, do not delete it. You can also reinstall the software after it is uninstalled. Generally, the software has a cache and does not need to be downloaded again.

I have installed VBOX, Smplayer, and Chinese language packs in ubuntu, and installed KDE4 desktop.

Of course, to uninstall ubuntu-desktop

Sudo aptitude install ubuntu-desktop

However, the best way to uninstall it is to copy the installation list on the terminal when you install it, so that you can uninstall it later.
