I started getting this message when running Dropbox on Ubuntu 22.04 LTS -

So I went to www.dropbox.com and downloaded the current version .deb installation file and used gdebi to unpack and install it. I get this message from that procedure -

So, now I can't use the old version of Dropbox which is compatible with my Ubuntu and I can't use the new version of Dropbox on my version of Ubuntu. And, BTW, please note the 'LTS' status of 22.04. I want to use the Long Term Support version of the OS if at all possible.
I've realized that I can just use the web version of Dropbox on my Linux system, and I will get by. If anyone out there has a relatively simple (!) fix for this I would appreciate your help.
