Troubles installing OpenOffice 3.4.1 on Kubuntu 12.04

[savao]

Hello.
I face with some troubles in installation process. When I install the packages in the /DEBS folder, it's was OK. But when I try to install packages in the /desktop-integration folder, I take follow text in terminal:
savao@savao-ProLiant-ML110-G5:~/Downloads/ru/DEBS/desktop-integration$ sudo dpkg -i *.deb

Please, tell me, what happened? Why system told me about LibreOffice? I Remove Libre before installation OOo

I find that before installing on Ubuntu (I expect the same for Kubuntu) I need to use Synaptic to remove libreoffice-core. If I do not do that, I get the error you report.
