I am trying to download an app called phyx
, which is necessary to use PyPhlawd (which is my final mission).
When running
sudo apt-get install git autotools-dev autoconf automake cmake libtool liblapack-dev libatlas-cpp-0.6-dev libnlopt-cxx-dev libnlopt-dev libnlopt0
(step 1 to install phyx
in Linux), I only get the following:
[sudo] password for mmlapeira:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libnlopt-cxx-dev
So I tried lots of things:
sudo apt-get update
sudo add-apt-repository universe
...
But nothing works, it won't locate the package.
I am completely new on this, so please I need a step by step answer.
