When I use the command :

sudo apt-get -f install libvpx*

I get the following error :

Unpacking libvpx1 (from .../libvpx1_1.0.0-1_amd64.deb) ...
dpkg: error processing /var/cache/apt/archives/libvpx1_1.0.0-1_amd64.deb (--unpack):
 trying to overwrite '/usr/lib/', which is also in package libvpx 110-1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

But I checked /usr/lib There is no present in the directory.

It's not that the file exists already. It's that there is a potential conflict if you install both packages. – hexafraction Dec 21 '12 at 12:54

If you only intend to install the libvpx library package, open a command terminal (Ctrl-Alt-t), and run the command sudo apt-get install libvpx1.

By, including the wildcard * in your command (using libvpx*), you are requesting a number of other files and potentially numerous dependencies.

I was able to solve the issue by following below mentioned steps :

Go to directory /var/cache/apt/archives/ Use the command : sudo dpkg --unpack --force-all ./libvpx1_1.0.0-1_amd64.deb

Note that using "force-all" option is important.

This forcefullly installed the libvpx debian package & the issue got solved.

Thanks for all the replies.
