My jaw dropped. I did not get that dependency failure (I tested this on my own machine before making this post) and it took me a moment to figure out why...
I am using Nemo 5, on purpose, on Zorin OS 16.
What comes in the repositories is 4.something-whatever and whenever I want a higher package I kinda just do whatever I want...
So. The same thing would probably work for you.
But before I go typing out how to upgrade to Nemo 5 - Is that the course you wish to take?
