How do you connect via sudo? The classical short file name, "/sudo::"?

This looks weird. "/sudo:user:" means to collect the machine "user" as
user "root". If you want to connect as user "user", you shall use
"/sudo:user@:"

Indeed. And here I am :-)

That's a side track, but maybe you show how it fails.

Again, how does it fail?

No, they are contained in the upcoming Emacs 26.1.

Try the changed syntax I've recommended above. If this doesn't work,
show how Tramp from the development fails, and let's fix it
together. Afterwards, we could investigate your problem on recent sources.
