You might want to consider moving it to the dev channel in update settings. That way if you don't want to try 16.04 yet, you will have the ability to update from your phone rather than the installer on or around the 30/08(ota5).
Until then 16.04 if you want to try it will need the installer that includes ota4 at the end if this month.
Also nearly forgot 15.04 is not getting any updates so you may as well be dev anyway its as stable as 15.04 will be.

I'm not sure every step is necessary, but I'll list them just in case.

  • Laptop running Ubuntu 18.04
  • Installed ubports-installer_0.1.9-beta_amd64.deb via command line (not Ubuntu Software) using 'sudo dpkg -i ubports-installer_0.1.9-beta_amd64.deb'. 1.20-beta failed repeatedly despite trying the deb, snap, and various permutations of this list.
  • I had installed and reinstalled various versions of the OS on the Fairphone 2, but a fresh install of Fairphone Android manual switcher (fp2-sibon-18.04.1-manual-switcher) worked.
  • Enabled developer mode with USB debugging enabled.
  • Selected 'trust device every time'.
  • Allowed ADB access to apps.
  • Launched Ubports using CLI: 'sudo ubports-installer'
  • Stepped through the wizard, using 15.04-stable, and wipe device.

Now I'm enjoying Ubuntu Touch - thank you!

in github is stated that the issue might be fixed. Maybe you can give it another try. I will do so later.

I'm now on 16.04/rc and just now got the W26 OTA update. 🙂

I also had to reflash my FP2 with android stock image, because the ubports installer version 0.1.13 "broke" it.
After that I used the ubportsinstaller 0.1.9 and it worked like a charm...

It's basically this: https://z3ntu.github.io/2017/06/16/Signing-boot-images.html

I tried to fiddle around with the ubports-installer sources and added some debug output to see the exact command that fails and gives the "FAILED (remote: bootimage: incomplete or not signed)" error:

fastboot boot "~/.cache/ubports/images/FP2/boot.img"

If I sign the image according to the link above and use that instead, I don't get the error.

Edit: it seems this is already being worked on https://github.com/ubports/ubports-installer/issues/184 and the problem is not with the file being signed or not.

If you have trusty or xenial [*] running on your computer, you can try to install UT using the command line. You can also try to install that tool on bionic too, I heard it works but I haven't tried it myself on that distro.

sudo ubuntu-device-flash --server=http://system-image.ubports.com touch --device=FP2 --channel=ubports-touch/16.04/rc --bootstrap --wipe

EDIT: I've just remembered that that method worked on other devices but FP2 on the early days of 16.04 development. I think that's fixed now but I wanted to tell you. Anyway, you can give it a try.

[*] ubuntu-device-flash is only officially available for those releases

After a failed attempt at flashing 16.04/rc I had to resort to flashing a Fairphone Android stock image (urgh!)

Is there a .zip of the current 16.04 image I can flash manually, preferably with a "flash all" shell script? I'd be more than happy enough with that in the absence of a functioning ubports-installer.

this issue is still relevant for me. The workaround with the installer 0.1.12 is just to ignore the wrong image or whatever error occurs. In version 0.1.15-beta I can still not get beyond rebooting in fastboot mode.
