This question already has an answer here:

Problem:

I'm trying to install OpenCV (video analytics) and am following the Ubuntu OpenCV installation documentation.

The provided script has a line which executed for some time, taking away more packages than I expected (such as ubuntu-studio video):

sudo apt-get -qq remove ffmpeg x264 libx264-dev

When the script gets to the line below, it bombs:

sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm libtiff4-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg

The error messsage is:

E: Unable to correct problems, you have held broken packages.

Attempted Solutions:

I first ran Update-Manager, ran sudo apt-get update, rebooted, tried to run the above script line manually, and still no change.

Thereafter followed the answers given at:

I ran sudo apt-get install -f and nothing seemed to change. It did mention that some packages were no longer needed and could be removed by apt-get autoremove, so I ran that. It removed a number of packages, so I reran the install command above. Still same problem of held broken packages.

I then ran sudo apt-get -u dist-upgrade, part of the resulting response was:

The following packages have been kept back: gstreamer0.10-ffmpeg

I'm not sure what that means. I do know that it shows up in my Update-Manager and cannot be checked.

I then ran

sudo dpkg --configure -a

and then reran

sudo apt-get -f install

and the package was still not upgraded, though there was this very interesting comment;

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:
 gstreamer0.10-ffmpeg : Depends: libavcodec53 (< 5:0) but it is not going to be installed or
                                 libavcodec-extra-53 (< 5:0) but 5:0.7.2-1ubuntu1+codecs1~oneiric2 is to be installed
E: Unable to correct problems, you have held broken packages.

Then I ran

sudo apt-get -u dist-upgrade

It showed I had one held package, so I ran

sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade

It also exited without upgrading the package, so I ran

sudo apt-get remove --dry-run gstreamer0.10-ffmpeg:i386

And it gave me:

*The following packages will be REMOVED:
  arista gstreamer0.10-ffmpeg
0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded.
Remv arista [0.9.7-3ubuntu1]
Remv gstreamer0.10-ffmpeg [0.10.12-1ubuntu1]*

But when I reran

sudo apt-get -u dist-upgrade

It showed the package was still there.

*The following packages have been kept back:
  gstreamer0.10-ffmpeg
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.*

Thereafter, went into Synaptic PM and completely removed gstreamer0.10-ffmpeg.

Reran

sudo apt-get -u dist-upgrade

And was told

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

However, when I ran the original apt-get command to install opencv (first code at the top of this question), it still gave me the same broken package errors.

So I tried:

$ cat /etc/apt/sources.list

Thereafter, I ran:

$ sudo apt-get check

Reading state information... Done

However, no resolution of the problem yet, as I still get the same broken package message when I attempt to run the install of OpenCV with this command:

sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm libtiff4-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg

But when I run the OpenCV install command, I still get:

E: Unable to correct problems, you have held broken packages.

So then I started almost completely over again, this time adding back in repositories that the upgrade to Precise had disabled.

Then I reran the following commands:

$ sudo apt-get autoclean

Result:

But I still get this error when I try to run the OpenCV install command:

E: Unable to correct problems, you have held broken packages.

What else do I need to do?

Will an upgrade to Ubuntu Studio 13.xx solve this problem (or compound it)?

Ok, I've run in the same problem that you (but with another packages). So as cheap solution I instead of apt-get used aptitude:

sudo apt-get install aptitude
sudo aptitude install libopencv-dev build-essential checkinstall cmake pkg-config yasm libtiff4-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg

it will offer you a solution to your dependencies, in my case:

The following actions will resolve these dependencies:

      Remove the following packages:                       
1)      libcupsimage2-dev                                  
2)      libsane-dev                                        
3)      libtiff5-dev                                       

      Keep the following packages at their current version:
4)      libcv-dev [Not Installed]                          
5)      libcvaux-dev [Not Installed]                       
6)      libhighgui-dev [Not Installed]                     
7)      libopencv-contrib-dev [Not Installed]              
8)      libopencv-dev [Not Installed]                      
9)      libopencv-highgui-dev [Not Installed]              
10)     libopencv-legacy-dev [Not Installed]               
11)     libopencv-objdetect-dev [Not Installed]            
12)     libopencv-videostab-dev [Not Installed]         

I accepted the solution given, you can select N if the solution is too destructive (in my case it was just some -dev packages that most likely I'm not going to use anymore, but you must check yours). Then I re-ran the installation command again and everything was a OK.

Thanks @Braiam, I was able to resolve my issue, and have kept the output from the change so that I can refer to it in the future if I have any package dependency changes I need to make. Thanks again! –  Will Nov 14 '13 at 15:55
