Hello Linux Geeksters. As a reminder, Ubuntu 14.04 Trusty Tahr will be released tomorrow, in all the traditional flavors: Ubuntu GNOME, Kubuntu, Xubuntu, Lubuntu, Edubuntu, Ubuntu Kylin, Ubuntu Cloud and Ubuntu Studio.
Canonical’s tradition is to release a new Ubuntu system every 6 months, one system on the 17th of April and the other one on the 17th of October. And unlike the release of Ubuntu 13.10 Saucy Salamander, which was considered boring by the community, Ubuntu 14.04 will come with a lot of enhancements and new features, including: Kernel 3.13.9 as default, a feature for minimizing the windows by single clicking the launcher, locally integrated menus (a feature also present on GNOME 3.12), improved shutdown dialogs, a new feature that allows the users to increase the volume up to 200%, a rewritten Unity 7 with support for window filtering by title, Unity Control Center as a replacement for GNOME Control Center, and of course, a new default wallpaper and 11 other pretty wallpapers submitted and voted by the community. Also, the Login Screen and the Lock Screen have been made to look identical.
In this article I will show you how to upgrade from Ubuntu 13.10 Saucy Salamander, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, to Ubuntu 14.04 Trusty Tahr, via the command line.
All you have to do is install the Update Manager Core:
$ sudo apt-get install update-manager-core
