I manually downloaded the latest deb files for LibreOffice 5.4.2 from LibreOffice's official website and installed LibreOffice 5.4.2 from the deb files.
But I realized I won't get automatic updates for LibreOffice, so I would like to add this PPA to my repositories:
sudo add-apt-repository ppa:libreoffice/ppa
I haven't run the above command, and have a question. Will adding a new PPA for LibreOffice update the LibreOffice that I just installed from the LibreOffice official website? Or shall I uninstall the LibreOffice that I just installed and install from the PPA, in order to get auto update from the PPA?
