apt - How to downgrade to a specific PPA version of LibreOffice?

Since 2012 I have been using LibreOffice provided by this PPA. But yesterday, I made an upgrade which contains a bug that messes with all my Sheets.

While I wait for a fix, I want to downgrade from the current version 4.2.0.4 to the previous version 4.2.0.3.

I've found several articles to downgrade from the PPA to "default" version 3.6 but none that downgrade to a specific PPA version:

Is it possible to do a version downgrade using standard apt commands?

It is, just do sudo apt-get install libreoffice=version. It will downgrade, remove and install to whatever version you want.
