Can't install programs

[mercury_may2112]

I tried doing:

sudo apt-get install vlc

But what I got was:

The following packages have unmet dependencies:
kmplayer-konq-plugins: Depends: konqueror but it is not going to be installed
konq-plugins: Depends: konqueror (>= 4:3.5.8-1) but it is not going to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I also have Kubuntu desktop installed with sudo apt-get install kubuntu-desktop and I want to get rid of it. how would I do that?

[tamoneya]

sudo apt-get -f install vlc
sudo apt-get remove kubuntu-desktop
Should solve both problems.
