cannot install software by using .deb file

you could download VLC from synaptic packagemanager. Which gives you all poss. dependec.
there is also a VLC ppa source on launchpad to download the newest VLC version.
: https://edge.launchpad.net/~c-korn/+archive/vlc

You can do this for installing both of these softwares:

sudo apt-get install vlc wine

Put this command into the terminal, which you can find Applications ->
Accessories -> Terminal.

Other than that, next time you want to install a .deb, go the the
terminal and do this:

sudo dpkg -i package_name
