Plamen made clear in another thread that Brax 3 doesn’t presently have the resources to keep working on the Ubuntu Touch port, and said it’s a community port at this point. Somebody who I think is the maintainer of the port of another UT device replied asking how they can help, and said last time they tried, merge requests weren’t being accepted.. there was no reply to this, at least publicly.
The UBports Foundation, which took over maintaining UT when Canonical abandoned it almost ten years ago, does not handle device ports - these are done by the community. I’m not aware of any individual who has taken on this device. To my understanding, unless some individual/group takes this on, or Brax 3 takes it back up, there won’t be further progress.
Many devices that run Ubuntu Touch are largely maintained by one individual, who is by no means working at it all that frequently. But the initial process of getting UT running well on a given device can take some real work, and I’ve never been clear how functional the Brax 3 team got things before stepping away.
So it’s hard to know how much work this would take. Probably not tonnes. But at present so far as I can see, nobody is doing it.
