Aptitude and apt-get behave differently when _removing_ packages. Aptitude keeps track of which packages were install because the user directly requested that they be installed and which were installed in order to satisfy a dependency. Then when the user request that a package be removed, it checks its database of packages that were installed to satisfy a dependency and also removes those 'dependancy satisfying' packages that can be removed because no other package needs them. In most cases this is good, but it can lead to aptitude doing really bad things in some special situations. For instance, I once installed kde by requesting the single over-all package that exists only to bring in all the packages needed to give the user a standard kde set-up. Then, after using it for a while, I decided that a lot of what was there was stuff and clutter that I didn't want. I tried to remove the stuff that I didn't want, but aptitude wouldn't do it, because it insisted that I had to remove the over-all kde package first. But when I removed that, it threatened to remove _all_ kde packages, which is not what I wanted. I used apt-get to remove the package kde. This made all of kde's component packages into independent packages in the little mind of aptitude. Then I removed the ones that I didn't want without aptitude trashing the rest of my kde set-up. So, both are needed, at least until users like me understand aptitude internals better. -- Paul E Condon [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
