Date: Mon, 24 Jan 2022 19:49:56 +0000 (GMT)

emacs -Q
C-x C-f
type: "//ssh:" -> expectation: start completion, first host, then
directories / files on host. However, nothing meaningful happens...

Note: with only fido-mode, it is possible to open a tramp connection,
but trying to change the directory deletes the whole line (//ssh:...)
instead of only the directory. This means one has to start from scratch
typing the connection details etc.

In your recipe, ypu don't mention enabling fido-vertical-mode. Running
your recipe as-it-is works for me as expected.

With fido-vertical-mode enabled, this is bug #51386 and #52758, I'm
merging this bug with them. It is an unfortunate problem Tramp cannot
solve alone.

Hmm, this I cannot reproduce locally. Perhaps you have typed three
slashes "///" in order to change the directory? Could you pls give an
exact recipe, starting with "emacs -Q"?

Best regards, Michael.

Indeed. The function in question is icomplete-fido-backward-updir, which
behaves as described. It doesn't take into account remote file names.

Whether this is intended or not, I don't know. Bug#43925 covers this
partly, but it isn't about remote file names, and it is applied to Emacs
29 only. I've added João Távora in Cc, the author of fido-mode.

Indeed, I forgot to add "fido-vertical-mode" to the recipe, sorry about that.

What I type is this:

emacs -Q
fido-mode
C-x C-f
//ssh:hostname:~/
DEL

for me, this then deletes the whole line. 

fido-mode
C-x C-f
//ssh:hostname:/etc/
DEL
DEL

also deletes the whole line, maybe that is what is suppoused to happen?

Thank you!!
