Canonical recently released Ubuntu 18.04, the company's latest iteration of its popular Linux distribution, nicknamed Bionic Beaver. Ubuntu 18.04 is a Long Term Support (LTS) release and will receive updates and support from Canonical until April 2023. But more notably... Unity is gone. GNOME is back. And Ubuntu has never been better. Scott Gilbertson
I just set-up 18.04 on an old Macbook Air and I'm having a lot of fun with it.
