I've tried to reproduce it with Emacs 26.3 as provided by Ubuntu 19.10,
but it works for me. *ls returns the requested file names.

I had to modify your example slightly:

* use sudo instead of su
* expand default-directory due to ~/

So I have applied

cd (concat "/sudo::" (expand-file-name default-directory))

But this shouldn't make a difference wrt the problem. I have also
started Emacs with "-Q", in order to suppress any config. Could you do
it also? I see ido in your messages, for example.

Best regards, Michael.
