Installing: Passwordless Sudo

[rr326]

Issue Description The gravity-sync install script requires a sudo password, even when you properly have passwordless sudo set up.

Why it matters: I have scripts to install my system (ansible, actually). But I can't install gravity-sync that way since it blocks on "enter password".

It's particularly weird because passwordless sudo is definitely working for my install user.

Configuration Details (Ignore the 'no route to host' - I've got different issues on this particular install. But the passwordless issue has happened on 3 different new installs.)
