At the point when Canonical’s Ubuntu Linux 18.04 showed up, this exceptional Linux appropriation had just a single little issue: You couldn’t legitimately hop from the keep going Long Term Support (LTS) variant, Ubuntu 16.04, to the most recent rendition. Presently, with the arrival of the principal point Ubuntu 18.04 update, Ubuntu 18.04.1, you can at last do it no problem at all.
Obviously, you could generally refresh from one form of Ubuntu to the next. You simply needed to have your home index on another segment or drive. Since the vast majority don’t waste time with that, updating was a task.
Before causing the move to recall Ubuntu 18.04 doesn’t look or feel like 16.04, 16.10, 17.04, or 17.10. That is on the grounds that Ubuntu has moving back to GNOME for its default work area from Unity. On the off chance that you need to stay with Unity, you should go through the motions to supplant GNOME with Unity.
