I just ran an apt-get install, and this is the output I get.
$ sudo apt-get install opencpu

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.
