OK, "uk" is available.

That's the problem: Emacs 25 had a bug which prevented it from
accepting Aspell versions that ended in "-rcN".  Emacs 26 fixes this.
You can apply the patch below to ispell.el and recompile ispell.el,
then it should work again.  (Alternatively, you could up- or
down-grade to a version of Aspell whose number doesn't end in "-rcN".)

This is normal.  What is NOT normal is that the dictionaries present
on your system are not included in the list.  And that happens because
Emacs failed to recognize your Aspell as such.

No, not with Aspell and Hunspell.

Here's a patch that should fix your use case:
