Something to make note of here. You should be using apt instead of apt-get (this is deprecated)

Where did you find that apt-get is deprecated? apt is just a nicer front-end to the apt-* tools and shouldn't be used in scripts because the cli is not guaranteed to be stable. not that it matters much for simply installing some packages though.

Ah nevermind, I guess it's "advise against" for basic user use, but otherwise, since it's being used in a script here, using apt-get makes sense. So disregard what I said.
