Fastboot: booting...FAILED (remote: bootimage: incomplete or not signed)finished.
@advocatux Hello I seemed to have fixed the issue. It is not a tool problem, but one of the installer. The tools are called asynchroniously and eventually hindering each other. I will clean up my code and send the patch to the maintainers.
@humungus perfect, I'm glad you found a solution
I'm eagerly awaiting this update too. 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.
Hello, afaik the zip is build on the fly from the archives on the recovery system. I did not find a complete zip.

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-flashis only officially available for those releases
Hi on bionic I can not get ubuntu-device-flash (I am on aarch64 arch). I did not find the sources neither. I commented my fix on github. Best regards
@humungus ah I didn't know you're using aarch64

Not sure if it helps, but in the Fairphone forum there were some instructions how to sign TWRP images so that they can be used for a one off boot (without installing).
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.
@josepjc , @Scott-Marley :
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...
Cheers for the advice everyone, I also stumbled with the unsupported "ubuntu-device-flash" in bionic, but as @Luksus also mentioned, v0.1.9 worked fine for me too (eventually, took a couple of goes).
I'm now on 16.04/rc and just now got the W26 OTA update.
in github is stated that the issue might be fixed. Maybe you can give it another try. I will do so later.

Did the same as @Luksus.

Thank you all for helping my phone out of its misery
@polto just for the record, there's a new installer version with all those old issues fixed
I managed to install Ubuntu Touch on a Fairphone 2 using the following method. 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!

@james Great well done. 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.
@lakotaubp Wonderful, thanks for the advice.
@james YMMD, finally a working solution.Using the old installer (0.1.9) did the trick.
