E: Error, pkgProblemResolver::Resolve generated breaks while uninstalling Mono

  • 772

I re-installed mono-runtime due to this error and it is solved.
But now I want to uninstall it (but in Ubuntu 13.10). So this is what happens:

hogar@hogar-desktop:~$ sudo apt-get purge mono-runtime

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

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

I looked at this very popular post but in this case I'm not installing a package. So not very sure

Any idea?

Additional info:

  • My /var/log/dist-upgrade/apt.log file is empty.
  • The command dpkg --get-selections | grep hold returns nothing
apt

    arg! It's just apt-get being silly, you need aptitude to solve problems:

    sudo apt-get install aptitude
sudo aptitude -fy remove mono-runtime

    That should deal with it.

    A resume of the problematics packages:

    • libgtk2.0-cil this is really a mono dependency. Unless you use Banshee you won't need it.

      CLI binding for the GTK+ toolkit 2.12

      This package provides the atk-sharp, gdk-sharp, gtk-dotnet, gtk-sharp and pango-sharp assemblies that allow CLI (.NET) programs to use the GTK+ user interface toolkit 2.12, ATK, Pango, GTK.NET and GDK.

      GTK# 2.10 is a CLI (.NET) language binding for the GTK+ 2.10 toolkit

      This package contains the GTK# assemblies

    • libmono*

      Just some mono dependencies, and you want to uninstall it.

    All in all, all the packages are easily removable, and I'm actually thinking that they didn't get installed in the first place. You can check using:

    dpkg -l libgtk2.0-cil libmono-corlib4.0-cil libmono-system-web-services4.0-cil libmono-system4.0-cil monodoc-manual | grep -v 'ii '

    If no package shows, then you can be sure that none were installed in first place and is just apt-get doing your life impossible.
