Bug#961829: libghc-xmonad-dev: package is uninstallable due to unmet dependencies

[Brian Paterni]

Package: libghc-xmonad-dev
Version: 0.15-1
Severity: important

Dear Maintainer,

I recently upgraded to Debian unstable on a new machine. One step in
setting up the system is getting xmonad running. Howeer this is made
more difficult since some additional modules needed to compile the
config file seem to be uninstallable at the moment. When I attempt to
install libghc-xmonad-dev, I'm met with the following output:

  $ sudo apt install libghc-xmonad-dev
  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:
   libghc-xmonad-dev : Depends: libghc-x11-dev-1.9-14ff7
                       Depends: libghc-base-dev-4.12.0.0-a86a1 but it is not installable
                       Depends: libghc-containers-dev-0.6.0.1-b7319 but it is not installable

                       Depends: libghc-unix-dev-2.7.2.2-dbe0e but it is not installable
                       Depends: libghc-utf8-string-dev-1.0.1.1-e1b76
                       Recommends: libghc-xmonad-contrib-dev but it is not going to be installed
  E: Unable to correct problems, you have held broken packages.


I do have other, existing machines that have the dependencies installed
and are able to compile the xmonad.hs config file fine. So perhaps this
is a regression that popped up somewhere in the stack at some point?

Thanks for any help!
:)
