You can live safely on the edge, using LibreOffice via appimage.
Libreoffice.org is has the best appimage support I ever officially found on a application: check it out over at
https://www.libreoffice.org/download/appimage/
there's a fresh, a stable version... They have it all, you can run multiple versions of LibreOffice this way (no need to uninstall the one you have installed in your system).
If you are not that aware of what appimages are, use your favourite search engine and look for info on it- it's basicly a single file packaging (basicly) all the files and dependencies the software needs to run. Download the Appimage you want, change permissions so it's executable, double click it, and that's it. No install needed. In my opinion it's what's snaps and flatpaks should be in terms of simplicity of use. If you want to "unisntall" just delete the Appimage and you'r done.
One note about file permitions: if you download a Appimage file to a non linux partition, you don't even need to change it's permitions, simply click it and it runs.
Running / getting direct links to Writer, Calc, etc Appimage versions is also possible, Just create links to the LibreOffice .appimage you want with one of the following options:
" --writer Creates an empty Writer document.
--calc Creates an empty Calc document.
--draw Creates an empty Draw document.
--impress Creates an empty Impress document.
--base Creates a new database.
--global Creates an empty Writer master (global) document.
--math Creates an empty Math document (formula).
--web Creates an empty HTML document. "
You can try thise via the terminal, if you want to - just go to the folder where you downloaded the Appimage to and run it.
EX:
1-open the terminal and cd to the folder where you have the Appimage you want to use then try something like this (using you'r "applicationXXX.Appimage" instead of mine (I've been trying out LO 6.3 since last year):
2- "./LibreOfficeDev-6.3.0.0.alpha0_2018-12-29-x86_64.AppImage --writer" opens up that LO Writer's version
Just a little bit trickier than using a installed from .deb or .tar Libreoffice version...
Note:
I never understand why Appimages get so little love, they are way easier to run than a flatpak (according to my limited experience). I never tried using snaps, so, I'm not really sure how they compare to Appimages...
