First run "sudo apt-get upgrade" which will upgrade all packages. If
that doesn't fix the issue you can use "sudo apt-get purge libreoffice-
core" and "sudo apt-get purge libreoffice-base-core" and then install
libreoffice-writer, which will grab the correct dependancies. If this
resolves the issue
I found out that the problem was wireless connection did'nt work with Software
Center.
Connected with cable, and now it's working.
But trying install Libre Office Writer, I get this:
The following packages have unmet dependencies:
libreoffice-writer: Depends: libreoffice-core (= 1:3.6.2~rc2-0ubu
