^^^^ Will Ubuntu GNOME upgrade to Ubuntu 18.04, or will support discontinue when 18.04 is released?? Just want to know what's better to run right now so I can upgrade and not have to reinstall later(I intend to see this transition through)-- GNOME installed correctly on vanilla Ubuntu, or Ubuntu GNOME?
They're both merging into one package-set by the sounds of it... So whatever you're most comfortable with now would be my answer.
Even were that not the case, switching desktop environments isn't hard. Certainly nothing that would stop me using what I considered to be the best choice for the next few months.
