[Bug 1988819] Re: When apt keeps back packages due to phased updates, it should list them separately

[Julian Andres Klode]

One thing I just noticed is that if you have something like gnome-shell
and mutter where gnome-shell depends on the new mutter and only mutter
is "not for us" we end up with something like:

The following packages have been kept back:
  gnome-shell gnome-shell-common mutter

with phasing specific message this would look like this:

The following packages have been kept back as they are phasing:
  mutter
The following packages have been kept back:
  gnome-shell gnome-shell-common

Because we kept back mutter and it is phasing, but the gnome-shell
update is not anymore, it is kept back because it has broken
dependencies on the mutter that is phasing.

Title:
  When apt keeps back packages due to phased updates, it should list
  them separately

Status in apt package in Ubuntu:
  Triaged

Bug description:
  After phased updates have been introduced, it may happen that apt
  upgrade shows packages as upgradable but ends up not upgrading them.
  In this case the packages are indicated as being "kept back".

  Unfortunately, the feedback provided about this to the user is not
  very informative. The user sees the packages being kept back and
  thinks something is going wrong on the system.

  When packages are kept back because of phased updates, apt should say
  so e.g., it should say that the upgrade is delayed.

  Incidentally note that aptitude does not respect phased updates.
