Canonical has been busy last 6 months to port Ubuntu on mobile devices, and Nexus 7 is the first device of this kind that will run a full Ubuntu installation. This will make Ubuntu maybe the first operating system to have the same code base and OS for tablets, smart-phones, desktop, to powerful workstations, servers and supercomputer.

Hopefully, this is going to happen soon as developers claim that the project is nearing its completion and Raring Ringtail is almost ready to run on mobile devices.

One of the big things that have been fixed are:

• Onboard, the virtual keyboard that got a major release recently with most bugs fixed and better touch screen integration
• Unity has been polished more and nux bug has been fixed
• The new raring images use oem-config to present us with an installer window, where you can specify a user name, the wireless network you want to use and other bits.

Earlier, users needed to use an external PPA to make Raring run well on Nexus 7, but hopefully now they will be able to do it without much efforts.

Daniel Holbach one of the developers wrote:

So what does this mean for you now? You can now very easily put Ubuntu 13.04 on your Nexus 7. It won’t need any additional PPA, it’s stock raring, you won’t have to reflash, but can just do your regular updates and enjoy the latest and greatest improvements day by day. This is a huge achievement and will allow us to do better and more immediate testing and hacking on the device.

In case you want to install Ubuntu on your Nexus 7 tablet, you can get the installation instructions from here. If you run into problems, you can always get in touch with developers at #ubuntu-arm on freenode.
