Peter, Looks like I'm going to do a clean install of thelatest Mint Cinnamon. No upgrades are available for 20.1. If I use timeshift to backup my system will it put the 20.1 back on the system?
I don't know much about Linux Mint, so it's hard to say. But I wouldn't be surprised if your old software won't run on the latest Mint. And the .deb package you want to install won't run on your old Mint, so that's a bit of a pickle. Normally the easiest solution would be to keep the old machine on 20.1 and install the new Mint on a new one (until you install the appropriate new software versions on the new one so that you can switch to it permanently.) But I don't know whether this is an option in your case. Maybe someone else on this list who knows more about Linux Mint will be able to offer more substantial help.
