I use ubuntu 19.01 and i soon will upgrade to the latest 20.04 but i need to upgrade my libreoffice. What should i do, i dont want my system to crash, that is why i will like to hear from you. Thanks.
There is no Ubuntu 19.01 - you surely mean 19.10.
Where is your current package coming from - is it a snap package, a flatpack package or from LibreOffice PPA (which one?). I'm asking since 6.3.2.2. doesn't seem to be from the current 6.3 PPA, which currently delivers 6.3.5.2
