Ubuntu AIO DVD (all-in-one), a collection of the most important Ubuntu 14.04 LTS flavors made available on April 17, 2014, is now ready for download.Canonical released its latest Ubuntu 14.04 LTS distribution back in April, and along with it all the other famous flavors were also offered. There is a single problem with this launch, namely that the distros come as separate operating systems and you will have to download five ISOs, including the original, if you want to have all of them.
The Ubuntu AIO DVD was put together by Milan Rajčić and helps users have all the major Ubuntu spins on a single DVD: Ubuntu 14.04 LTS, Kubuntu 14.04 LTS, Ubuntu GNOME 14.04, Xubuntu 14.04 LTS, and Lubuntu 14.04 LTS.
There are some caveats to this collection. For example, not all the official flavors that are based on Ubuntu have been integrated, which means that Ubuntu Server, Edubuntu, Mythbuntu, and Ubuntu Studio are not present. Also, Ubuntu, Kubuntu, and Ubuntu GNOME feature only the 64-bit version, and Xubuntu and Lubuntu are only present in the 32-bit release.
As you can imagine, this is a very large compilation and it holds the official images that you can also download from the Canonical servers. The difference is that users have a single image that holds them all.
Ubuntu 14.04 LTS (Trusty Tahr) was deemed a success by its developers and the adoption rate for the new system has been high. Given the fact that Ubuntu 13.04 has just reached end of life and Ubuntu 13.10 only has a couple more months to live, it's likely that more users will flock to the new Ubuntu 14.04 LTS.
If you are not familiar with the official Ubuntu flavors, here is a rundown: Ubuntu is the base operating system developed by Canonical and comes with the Unity desktop environment, a piece of software made by the same developers.
Kubuntu is built by the community and is based on KDE SC, another type of desktop environment. In the case of Kubuntu 14.04 LTS the latest KDE available is 4.12.3.
Ubuntu GNOME is a newer member of the Ubuntu family, developed by the user base as well. As the name implies, this is a distro built with GNOME, in this case 3.10.
Xubuntu is also developed by the community and comes with the Xfce desktop environment, which is a lighter solution for people who want a more conservative desktop, although it can be greatly customized.
Lubuntu is probably the lightest official flavor of Ubuntu and it's based on LXDE. It's been around for quite some time, and it is recommended for older systems.
