Linux AIO is a project to package multiple flavours of a distribution in one ISO within a DVD size limit. Users can try each flavour live or install on their systems. In essence the difference lies mostly in the desktop environments. This is an invaluable source of distributions for distro hoppers. Note that there are issues, some of which are unresolved due to distro dependencies. However, for most of it, the stuff works.

The project supports a large number of Primary distributions:

Ubuntu [Ubuntu, Kubuntu, Ubuntu GNOME, Ubuntu MATE, Xubuntu and Lubuntu]

Linux Mint [Cinnamon, MATE, KDE and Xfce]

LMDE [Cinnamon and MATE]

Debian Live [GNOME, KDE, Xfce, Cinnamon, MATE and LXDE]

Fedora [Desktop, KDE, LXDE, Xfce, MATE]

Secondary distributions differ in the way AIO boots and release cycle:

ALT Linux

Korora

PCLinuxOS

Point Linux

Porteus

ROSA

SolydXK

Tanglu

Trisquel

Zorin OS

The latest addition to the family is Ubuntu 15.10 (x86, x86_64 and mix). Grab it in the downloads section.
