Package dependencies cannot be resolved

Question

I am using Ubuntu 12.04. When I try to open a video file like a file with an .mkv extension with mplayer it says it requires some multimedia plugins like gstreamer.

When I tried to install the required multimedia plugins in the Ubuntu Software Center this error message appeared.

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

When I tried to install the required multimedia plugins in the terminal this error message appeared.

 The following packages have unmet dependencies:
gstreamer0.10-ffmpeg: Depends: libavcodec-extra-53 (>= 4:0.7.3-1) but 4:0.8.3ubuntu0.12.04.1 is to be installed

I searched and found that the most solution said:

sudo apt-get clean
sudo apt-get autoclean
sudo apt-get install -f

and I tried them and nothing happened.

Looking at your error messages, I guess you either installed packages which are newer version than the standard repo (I might not the case) or installed packages which depends on the older versions of packages (Most probably) and it is not updated for the latest dependencies (thus requiring older versions).

I suggest you to do these: (most of the cases, it works)

Install aptitude with sudo apt-get install aptitude command
Try to install the package you are willing to install with command like
```
sudo aptitude install <package-name>
```
Aptitude will show you the error and present you a possible (best) solution. You will be asked to choose from 3 options with a message like
```
Accept this solution? [Y/n/q/?]
```
If you see that your desired package is not listed in the (will be) installed list, simply press n to let aptitude give you the next best solution. After several trial, (if you are lucky) you will see that your desired packages are in installable list and the packages causing the dependency problems will be showing in downgrade list. In this stage Press Y to accept the solution. The packages will be downgraded to satisfy to installation request.

I'm sorry that, I can't give you a demo run of aptitude like this, but you can check this page to see some of it's action.

the problem is that i don't know the name of the package because the program is responsible for choosing the plugins he want — amrro, Oct 13 '12 at 02:40

Clean your cache and redownload the packages sudo apt-get clean sudo apt-get autoclean

Try with sudo apt-get install -f , I've been getting these errors too.

Go to ubuntu software center >> Edit >> Software Sources >> Download From >> Select United States After that restart your computer go to software center and type wine and install it

sudo apt-get update to update your package list sudo apt-get autoclean to clean up any partial packages sudo apt-get clean to clean up the apt cache sudo apt-get autoremove will clean up any unneeded dependencies

Open the terminal and copy and paste all this code:

sudo apt-get clean &&
sudo apt-get autoclean &&
sudo apt-get autoremove &&
sudo apt-get update &&
sudo apt-get upgrade &&
sudo add-apt-repository ppa:ubuntu-wine/ppa &&
sudo apt-get update &&
sudo apt-get install wine1.5

IF THI NO WORK, TRY THIS: I suggest you to do these: (most of the cases, it works)

Install aptitude with sudo apt-get install aptitude command

Try to install the package you are willing to install with command like

sudo aptitude install <package-name>

Aptitude will show you the error and present you a possible (best) solution. You will be asked to choose from 3 options with a message like

Accept this solution? [Y/n/q/?]

I'm sorry that, I can't give you a demo run of aptitude like this, but you can check this page to see some of it's action.

If, while doing this, you can identify the broken package, this command will very forcefully remove it:

sudo dpkg --remove -force --force-remove-reinstreq packagename Replace "packagename" with the real name, of course.

I had the same issue as you. You just need to be careful and only select the codecs for your architecture of device. To do so, make the window telling you about the codecs big so you can see the full name of the packages. If you have a 32-bit processor, select the ones with i386 at the end. But, if you have a 64 bit processor, choose the ones without i386 at the end.
