As previously promised, Canonical has released a software tool that allows you to install Ubuntu Linux on the Google Nexus 7 tablet. Actually, this program is called Ubuntu Nexus 7 installer, and using this installer, installing the specified distribution on the tablet is quite simple.
In addition to the software package, you need a computer running Ubuntu, a Nexus 7 tablet, and a USB data cable to connect the tablet to a PC or laptop.

And yes, you need to unlock the tablet loader. If you have not done so, then be careful - the data from the "pill" will be erased.
In addition, installing Ubuntu will also erase the data from the tablet. If you plan to return to Android, it is worth making a backup using TWRP or ClockworkMod, and then copying the backup files to a PC or external storage device. Thus, if necessary, you can reinstall Android (use
the Canonical instructions ), re-root the device and reinstall ClockworkMod or TWRP. Then we restore all your data to the state before installing Ubuntu.

Well, let's go back to installing Ubuntu on Nexus 7. So far, Canonical has released a rather “raw” version of the distribution. In fact, you will be installing a desktop version of Ubuntu on your tablet. True, both the touchscreen display and the ARM platform are supported, there are no problems here.
The goal of Canonical is to allow developers to try out this OS on tablet PCs, using Nexus 7 as the most convenient platform for this. And only in 2014, the company hopes to release a unified distribution of the "tablet" Ubuntu, which, among other things, is also suitable for smartphones with tablets. Releasing the installer for Nexus 7 is just the first step in this direction.

Due to the “dampness” of the distribution, there are several unpleasant moments. So, the camera is not working. Bluetooth is not working. Automatic screen rotation does not work. Plus there are a few bugs affecting memory, sound, and more. But we must remember that this is a distribution for developers and testers, and not for ordinary users.
The community manager, Canonical, showed a plan for releasing future versions of the Ubuntu Tablet version on
his blog . So, Ubuntu 13.04, adapted for tablets, will be released in April 2013. But the final adaptation of Ubuntu for the "tablets" will take about another year.
