multiple version of same package. How to clean ?

[cremersdh]

I have (after upgrading from 9.10 to 10.04) several packages who are installed with multiple versions.

e.g. Python

dpkg -l | grep python2
ii libpython2.6 2.6.5-1ubuntu6 Shared Python runtime library (version 2.6)
rc python2.4 2.4.6-1ubuntu3.2.9.10.1 An interactive high-level object-oriented la
rc python2.4-minimal 2.4.6-1ubuntu3.2.9.10.1 A minimal subset of the Python language (ver
rc python2.5 2.5.4-1ubuntu6.1 An interactive high-level object-oriented la
rc python2.5-minimal 2.5.4-1ubuntu6.1 A minimal subset of the Python language (ver
ii python2.6 2.6.5-1ubuntu6 An interactive high-level object-oriented la
ii python2.6-minimal 2.6.5-1ubuntu6 A minimal subset of the Python language (ver


I guess I only need the newest one .. The other ones have status "RC"
Or am I wrong here, and do I need to keep these old versions ?????

So how do I get rid off 2.4 and 2.5 and just keep version 2.6. How can I easily remove these "old" packages. I tried aptitude purge, aptitude clean, aptitude autoclean. But they don't do the trick.

I am looking for an easy way, because python is only an example. Else I could just delete them be using their name.... (of course)

Why did these stay on my system anyway ?

When you open Synaptic, you will see on the left side a selection that says Installed (Residual Config) or Auto Uninstall. Select all packages so marked and uninstall Completely.
