Aptitude Related

aptitude has a command line interface very similar to apt-get, if you like apt-get, then you will love aptitude. What aptitude has over apt-get is that it tracks which packages have been installed manually and which have been installed automatically (i. e. to fulfill dependencies). Automatically installed packages will be uninstalled as soon as they are no longer needed. I.e., when an automatically installed package is no longer needed when the last package depending on it is removed, aptitude will remove that too.

$ aptitude install fglrx-driver=

<package>=
       Place  <package> on hold: cancel any active installation,
       upgrade, or removal, and prevent this package from  being
       automatically upgraded in the future.

Or, directly

aptitude hold tetex-base tetex-bin tetex-extra
