Ah now that is interesting. I still have 6.3.5 on Z15.3Core.
Under Software>Productivity, Libre Office components shown ticked as installed are version 6.3.5. So good so far.
However, under Software>Recommended Productivity Applications appears Libre Office 220.127.116.11 available for installation.
So what I take from that is that Software Updater does not update Libre Office versions.
Do I need to remove 6.3.5 before I install 18.104.22.168. I assume that is the latest stable version. If I just install 22.214.171.124 will I end up with both?
