I have been attempting to install ubuntu-touch on a new Nexus 7 2013 (Android 5.0.2) from a laptop running ubuntu 14.04 LTS by following the instructions here:
Flashing the device fails with the message that the image didn't copy to /cache/recovery/ because it "Is a directory" - please see the output below. The device then boots into recovery but goes no further - i.e. doesn't install ubuntu as the OS.
Could anybody suggest a solution to this to enable a successful install of touch?
