qubes-dom0-update throws non-zero error code when package already installed

[r-cheologist]

Qubes OS version:

4.0-rc2

Affected TemplateVMs:

dom0

---

Steps to reproduce the behavior:

PROMPT> qubes-dom0-update qubes-template-fedora-26-minimal
... Complete!

PROMPT> qubes-dom0-update qubes-template-fedora-26-minimal
.... No match for argument qubes-template-fedora-26 minimal

Expected behavior:

Along the lines of plain qubes-dom0-update - it states No new updates available and gracefully exits with error code 0 when nothing is to be done. Maybe qubes-dom0-update <PACKAGE> should state something like Package <PACKAGE> already installed, but it should DEFINITELY NOT throw an error code 1.

Actual behavior:

If the package is already installed qubes-dom0-update <PACKAGE> states the misleading/false No Match for argument <PACKAGE> and returns error code 1.

Hmmm, I tried this with qubes-template-debian-9 (already installed) and it says "No packages downloaded... Nothing to do" and 0 return code. Can't reproduce on rc2.

"No match for argument" sounds like there was a typo in the command.

It looks like that might be happening here:

PROMPT> qubes-dom0-update qubes-template-fedora-26-minimal
.... No match for argument qubes-template-fedora-26 minimal
                                                   ^ Missing hyphen?
