How to "properly" downgrade LibreOffice versions deals with a downgrade from 3.5 to 3.4.*. Is there any way to nicely downgrade LibreOffice 4.0 to 3.6? The latter is not in the package lists.
Background: It is because of this bug which is about the incompatibility of an extension which should really be core functionality. Essentially, 4.0 just does not deal with templates in an intelligent way. You cannot fully apply a template to an existing document.
Update: based on
apt-cache showpkg libreoffice (found on How to Downgrade a Package via apt-get?) one can confirm that only LibreOffice 4.* is in the repositories.
