Not installable on Zesty (or Yakkety) since xchat-gnome has been removed

[Hans Joachim Desserud]

When attempting to install xchat-gnome-indicator on Zesty (or 16.10), I get the following error message:

$ sudo apt install xchat-gnome-indicator
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 xchat-gnome-indicator : Depends: xchat-gnome (>= 1:0.30.0~git20141005.816798-0ubuntu1) but it is not installable
E: Unable to correct problems, you have held broken packages.

Looks like xchat-gnome itself was removed a while back, see [1] and [2]. Since xchat-gnome-indicator has a strong dependency on it and is currently uninstallable, I believe this should have been removed alongside. I can probably be safely removed from zesty, and possibly 16.10 but I don't know how these things are handled in stable releases.
