I tried to upgrade my LibreOffice to 4.0 on my Ubuntu 12.04, but now it doesn't work anymore.
If I try to install LibreOffice again, I get the following output:

The following packages have unmet dependencies:

libreoffice : Depends: libreoffice-core (= 1:3.6.0~rc4-0ubuntu3~ppa1~precise1) but it is not going to be installed

           Depends: libreoffice-writer but it is not going to be installed

           Depends: libreoffice-calc but it is not going to be installed

           Depends: libreoffice-impress but it is not going to be installed

           Depends: libreoffice-draw but it is not going to be installed

           Depends: libreoffice-math but it is not going to be installed

           Depends: libreoffice-base but it is not going to be installed

                 Depends: libreoffice-gtk but it is not going to be installed

Would be so great, if anybody could help me!

Thanks!
