Howdy.
I use & prefer to keep U/M 18.04.5 .
I can tolerate Caja, but really do prefer Nemo & want it to just open instead by default.
Tried setting Nemo to default using 'Preferred Applications' and it did...nothing.

Wider searching brought these maybe pertinent results:
Which I'll not touch as they may or may not be the 'fix' which I desire.
Will someone please update this thread with confirmation of what actually does or will not work for this ??
Thanks for any helpful replies !!!
