FAQ: Removing KDE4 from mixed system

[Rog131]

This should be fairly straightforward. but sometimes it isn't.
This links to the Re: Be Free With KDE 4.0!


Removing packages

#1 Removing key packages : kdelibs5 kde4base-data kde4libs-data

In the konsole

sudo apt-get remove kdelibs5 kde4base-data kde4libs-data

or use your favorite package manager - FAQ: Package Managers .


#2 Removing packages that are no more needed (they depend key packages).

sudo apt-get autoremove

man apt-get

autoremove
autoremove is used to remove packages that were automatically installed to satisfy dependencies for some package and that are no more needed.

Optional

It is good to check first:

sudo apt-get -s remove kdelibs5 kde4base-data kde4libs-data

and

sudo apt-get -s autoremove

man apt-get

-s, --simulate, --just-print, --dry-run, --recon, --no-act
No action; perform a simulation of events that would occur but do not actually change the system.

And it is good to make notes:

logsave where_did_it_go.txt sudo apt-get -s autoremove

man logsave

logsave - save the output of a command in a logfile

Note
If you have "where_did_it_go.txt" => it is easy to install missing packages again.


ppa /1/ repositories have also KDE 3.5 packages and sometimes these packages can get your package management confused. To me the solution was to remove all ppa packages and install clean packages from the ordinary repositories.

Note
With synaptic package manager this is a bit easier. Synaptic package manager has search with "Version" -> No need to search and remove packages one by one.
