LibreOffice not updating

[Kevin O'Gorman]

I've got 5 machines running the Xubuntu flavor of Ubuntu, Focal Fossa LTS.
I'm not sure how I accomplished it, but all five have LibreOffice running
version 6.4.6.2.  I notice that Libre Office's current version is 7.1.4.2,
and I'd like to upgrade.  I don't see an option to do that (possibly short
of getting off my LTS and into a later Ubuntu -- but I'd rather not do
that).

I downloaded the latest .deb files from LibreOffice, and installed them.  I
still get the old LibreOffice when I use the usual "soffice' command or
'libreoffice'.

I'm missing something, I'm sure, but have no idea what or how to find out
other than asking here.
