  • Hi. After running both sudo apt-get update and sudo apt-get upgrade -y. When I get to this one:

    sudo apt-get install -y cmake g++-4.9 doxygen

    I get the following:

    Reading package lists...done
    Building dependency trees
    Reading state information...
    E: Unable to locate package g++4.9
    E: Couldn't find any package by regex 'g++4.9'

    How do I get past this step? I've installed ControlBlockService2 before but never got stuck here.

    Is there a typo? It should be g++-4.9and not g++4.9.
