The article mentions that it works fine on Ubuntu 24.04 LTS, so it shouldn’t be an issue unless you’re running something older than that.

What a terrible article. The margins for board partners is small, but Nvidias margin is huge.

Yes, I would recommend creating a backup (perhaps on your phone or a different computer over the network) and then upgrading to 21 and then 22. IMHO Mint has steadily gotten better and there is typically no reason to stay on an older version.
