Hi,
I have tried to reproduce your problem with a clean Ubuntu 16.04 VM, but all installation steps succeed for me. Unfortunately, I do not know the packaging system well enough to know what could possibly go wrong. You will therefore probably have to wait until after New Year before we can help you in solving this.

I'm trying to install flow on fresh Ubuntu 16.04 LTS (64 bit) (downloaded from https://www.ubuntu.com/download/desktop) I'm executing these commands: http://opm-project.org/?page_id=245 After executing sudo apt-add-repository ppa:opm/ppa sudo apt-get update I get error "NODATA": lopadren@lopadren-vbox:~$ sudo apt-add-repository ppa:opm/ppa The Open Porous Media (OPM) initiative provides a set of open-source tools centered around the simulation of flow and transport of fluids in porous media. The goal of the initiative is to establish a sustainable environment for the development of an efficient and well-maintained software suite.
