Because of a problem reported here, possibly a bug, I have to use LibreOffice 3.5.
But I would like to keep an eye on the latest version, which might even solve that problem.
I would like to use the latest 4.x version beside 3.5. (not in a virtual box or in wine)
That is: I have already installed 3.5 from a deb package. How to install now the 4.x version without conflicts?
I imagine I could uninstall 3.5 and put 4.0 in place and then try to install 3.5 separately. But how?
