Every time I try to use apt-get install or remove or purge on my Debian, I have this error pop up:

The following packages have unmet dependencies:
 libimage-magick-q16-perl : Depends: libmagickcore-6.q16-2 (>= 8:6.8.9.9) but it is not going to be installed
 libmagick++-6.q16-5 : Depends: libmagickcore-6.q16-2 (>= 8:6.8.9.9) but it is not going to be installed
                       Depends: libmagickwand-6.q16-2 (>= 8:6.8.8.9) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Then I go and run 'apt-get -f install' to try to fix it and I get another error:

nichadler@debian-server:~$ sudo apt-get -f install

Any help?

This is the error:

dpkg: error processing archive /var/cache/apt/archives/libimage-magick-q8-perl_8%3a6.9.1-2_amd64.deb (--unpack): trying to overwrite '/usr/lib/x86_64-linux-gnu/perl5/5.20/auto/Image/Magick/Magick.so', which is also in package libimage-magick-q16-perl 8:6.8.9.9-5 dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

dpkg is refusing to install the package because another package owns the file /usr/lib/x86_64-linux-gnu/perl5/5.20/auto/Image/Magick/Magick.so

By default, dpkg will not overwrite files belonging to another package - and "ownership" of files by particular packages can change when packages get renamed or a collection of packages gets restructured.

You need to either run apt-get with the -o Dpkg::Options::="--force-overwrite" option like this:

apt-get -o Dpkg::Options::="--force-overwrite" ...

or you can make this permanent by adding it to /etc/apt/apt.conf or a file in /etc/apt/apt.conf.d/ like so:

DPkg { Options {"--force-overwrite";} };

Try dpkg -r libimage-magick-q16-perl to remove the conflicting package manually and then do a apt-get -f install and apt-get install libimage-magick-q8-perl if it wasn't installed in the former step
