Urgent — Installing LO 7.1 on Ubuntu system

Can someone please give me the instructions on how to install LibreOffice 7.1 onto an Ubuntu 20.04 system??? ASAP please!!!!
I have both the DEB and RPM packages downloaded from the LO website, but having problems.
I think I will have to use Terminal and install LO 7.1 using the command line.

Thank you Dave.

LO 7.1 is now installed in my Ubuntu virtual machine on my Mac mini.
