No boot after update dev-chanel version 999

[Kutzi]

First thank you @Luksus for your great work to get Ubuntu Touch running on Fairphone 3(+). I use Ubuntu Touch daily on my Fairphone 3+ since it is available.

Hi everyone,

today i did an update from version 996 to version 999. After reboot the system didn't start anymore.

Extract from log file /cache/ubuntu_updater.log:

@Kutzi Hm, there is a hotfix in the pipeline, which will be released as OTA-26. Maybe it broke something... I assume, you are using the devel-channel?

Please try to reinstall with the ubports-installer (without wipe of course!).

[Luksus]

@Kutzi You can use the stable channel btw., since for xenial there won't come more new features and there is no benefit of using devel anymore.

[Kutzi]

@Luksus: Thank you for your quick response.

All the time i use devel-channel. That's why I haven't changed it yet.
Are there any efforts to port 20.04 for Fairphone 3(+)?

[Luksus]

@Kutzi there is already a focal-port. I am Using it for months now.
Just needs an update-channel to make it available to all users.
