packages kept back

[onoff]

I get that certain packages can't be installed:

Code: Select all

    $ sudo apt-get upgrade
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    Calculating upgrade... Done
    The following packages have been kept back:
      libgd3
    0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

After searching the web and trying several things I still can't remove this issue. I've tried to use `apt-get install -f`, checked for broken packages in synaptic (but there are none) and tried the distro upgrade. The issue is because of the unmet dependency of the following package:

Code: Select all

    $ sudo apt-get install -f libgd3
    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:
     libgd3 : Depends: libfontconfig1 (>= 2.11.94) but 2.11.0-6.7+b1 is to be installed
    E: Unable to correct problems, you have held broken packages.

What I then tried is to run a apt-cache policy with the following output

Code: Select all

 sudo apt-cache policy libfontconfig1
    libfontconfig1:
      Installed: 2.11.0-6.7+b1
      Candidate: 2.11.0-6.7+b1
      Version table:

         2.9.0-7.1 500
            500 http://debian.ethz.ch/debian wheezy/main amd64 Packages

how can I resolve this issue?

Mixing wheezy,jessie, and stretch?

how can I resolve this issue?

Option 1.

Option 2: Please feel free to try to resolve the issues using this manual instead Debian's and/or this picture as wallpaper.
EDIT: And use this dedicated forum.

Translation - reinstall from scratch and don't mix repos.
