I am rather interested in trying Ubuntu Touch on a Nexus 10, however I am a bit confused about the status of the port.

I checked the device page, and was happy to find, it's kind of working. I figured, I could get my hands dirty, and might aid the community with some contributions. Haven't done any Linux hacking recently, so it's about time.

My understanding is, that the device was abandoned by the official Ubuntu team, and has been picked up by Ubports. In accordance with this, the official build on the Ubuntu image servers are eons old, if anything. (I couldn't find any, but that might be me overlooking something.) However I couldn't find any code in the repository here on Ubports, but there are still a few system images available. So I am a tiny bit confused.

So where to start? Is there any point in trying it on Nexus 10? Is there any point in getting involved, or the device has been abandoned because some deal-breaker issue, which isn't expected to be resolved ever?
