Installation freezes on checking universe repository.

=== CMD ===: which yum

=== CMD ===: which apt-get

=== CMD ===: which xe

=== CMD ===: which xe

=== CMD ===: add-apt-repository universe

Adding component(s) 'universe' to all repositories. Press [ENTER] to continue or Ctrl-c to cancel.Aborted.

Easily fixed by adding -y to xo-install.sh
