How am I supposed to solved it.
I only get it to work using master branch of VLC
https://launchpad.net/~videolan/+archive/ubuntu/master-daily
first add the repository
sudo add-apt-repository ppa:videolan/master-daily
sudo apt-get update
sudo apt-get install vlc
The vlc-nox package installs vlc
To remove, use:
sudo apt-get purge vlc-nox
Next, to reinstall vlc, use:
sudo apt-get update
sudo apt-get install vlc
% sudo snap install vlc

Anybody else run into problems installing opencpu in Ubuntu 14.04 (LTS)?
You need to add the opencpu-1.5 ppa repository first:
sudo add-apt-repository ppa:opencpu/opencpu-1.5
sudo apt-get update
sudo apt-get install opencpu
Have a look at the server manual for more detailed instructions.
