I have two PC's that I try to keep the same with regard to applications. One is Dell Precision 7720 laptop and the other is a Lenovo M80 desktop.

On the Dell, snap version of LibreOffice (LO) upgraded itself from 7.6 to without any action on my part or any notification other than see the different number on the icons on the Unity Launcher.

On the M80, I had to download and install the *.deb file to get to replace 7.6.

So, first question is can I remove all the conventional version of LO ( that appears in Synaptic and not have any problems?

Second question is that the M80 has the same version number, but a different build number, AND added functionality. Under Tools/Options, there is an additional heading under Internet that is called Language Settings. Under Language Settings there is a subheading called English Sentence Checking with a number of options for having LO correct grammatical mistakes. Under Help, there is a new dropdown called Check for updates. The build version on the M80 begins with a "b" while the build version on the Dell begins with an "a".

Since LO is an integral part of Ubuntu, why isn't there more information available on these changes?

Thank you,
