Could you pls confirm, that <remote path to file> starts with "/home"?
And that on your local machine, "/home" is a symlink to
"/System/Volumes/Data/home"? If yes, your error is exactly the same as
bug#38648.

This looks like my suspicion. Hmm, if this is new in macOS Catalina, all
Emacsen are broken with the same.

There are no plans for an Emacs 26.4. Emacs 27 will start its pretest
soon, and I don't know whether this problem will trigger a hotfix release.

What we could do is to publish the patch of bug#38648 on top of Emacs
26.3. Since we haven't done such an announcement yet, I don't know where
to do it.

I believe there are other fixes in Emacs 27 for macOS Catalina, which
are not included in Emacs 26.3. Maybe a special cumulative patch of
Emacs 26.3, good for macOS Catalina, could be done?

Eli? John?

Best regards, Michael.
