How to completelly reinstall LibreOffice?

Question

I recently installed Ubuntu 16.04 (fresh installation), but I have lot of problems with LibreOffice. I am not more specific, as these problems seems of various nature, with windows not updating, crashing and so on. I had no problems in 14.04.

So, I would like to "reset" LibreOffice and reinstall it. What is the best way to reinstall all the LibreOffice packages in Ubuntu 16.04?

UPDATED: I did lookup for all LibreOffice packages in Synaptic and "purged" them before reinstalling, but I still have problems as you can see from the following screenshot (editing math formula is not the only problem, but it is the most repeatable one, so I am using it as a benchmark of things working or not)

Solution

I haven't encountered this problem myself, so I didn't have a chance to experiment the following solution myself. But, according to this blog post, this AskUbuntu answer and even this forum thread, the solution to your problem would be as follows:

Open Terminal by pressing Ctrl + Alt + T and type:

sudo apt-get remove --purge libreoffice*
sudo apt-get clean
sudo apt-get autoremove

@CristianaNicolae: yup, but libreoffice is a miriade of packages.. my question is how to be sure I am removing all the packages involved

Thank you. I solved purging again libreoffice and installing the debs directly from the LibreOffice site.
