Package: apt
Version: 2.4.1
Severity: minor
With "apt install ...", apt wants to install a package as a
dependency, but this package is already provided by an installed
package, via "Provides:".
Example:
cventin:~> apt install -s elpa-transient
[...]
The following additional packages will be installed:
emacs
but on my machine, emacs-gtk is already installed, and it has
Provides: editor, emacs, emacsen, info-browser, mail-reader, news-reader
Note: emacs is a metapackage for emacs-gtk or variants, so that
it is completely useless if emacs-gtk is installed directly.

elpa-transient Recommends emacs (>= 1:25.1)
emacs-gtk Provides emacs
An unversioned provides like the one from emacs-gtk does not satisfy
a versioned dependency.
So, APT is working as intended here, you will have to talk to the
maintainers of these packages to figure out which options there are
to reach your desired outcome.
I can not recommend a cause of action here as
a) I am a die-hard vim user and
b) have no idea if the Recommends is needed at all and/or if it would
make sense to version the emacs provides. The later would at least
accomplish your request… (see also vim & vim-nox which implement this).
That might be best discussion with the involved team(s) rather than some
bugreports in a few leaf packages.

With your logic, If you have vim installed, it is completely useless
to install emacs because both provide 'editor'.
While I think that is correct (see a) above), I don't think we can
implement that in apt, so I have to refuse your suggestion for hopefully
now obvious reasons and close the bugreport as: "Be careful what you wish
for."
