Debian Equivalent of Ubuntu 14.04 or higher, Fedora 21 or higher

[Martin109]

Dropbox is telling me I will probably need to update the OS on one of my machines, but stipulates this in terms of Ubuntu and Fedora (Ubuntu 14.04 or higher, Fedora 21 or higher).  How does this translate into Debian versions?

14.04 = jessie

So jessie / stretch / buster (older to newer).

( I just googled "ubuntu 2014.14 debian equivalent" and that was the first link.)

Many thanks Greenbank

Debian Stretch (9.5) in the current stable. There is no point upgrading to anything before that unless you needed to run non supported legacy software.

I tend to run Debian on a variety of older laptops.  My sense was, and I may have this wrong, that newer versions of any operating system assume greater hardware capability.  Minimum requirements seem to increase, sometimes by default, sometimes by declaration (eg Skype stating they can only deal with 64-bit Linux OS, not 32-bit).
