Engadget reports that Canonical has released an Ubuntu installer for the Nexus 7 tablet

If you'd rather not let your Nexus 7 live out its life as a Jelly Bean-toting device, Canonical's freshly minted Ubuntu Nexus 7 Desktop Installer can help. Instead of allowing Ubuntu to ride shotgun with Android, the installer requires unlocking the device's bootloader, which wipes the slate clean. Once the Nexus 7 is unlocked, started in fastboot mode and connected to an Ubuntu machine, the one-click installation software takes care of the rest.
