Status of Noble-based Ubuntu Touch (UTNext)

Since the last time I made a forum post, the following features has become usable:

GPS
NFC
Phone call & SMS
- Note that MMS is blocked until very recently. We'll have to recheck if it has been fixed or not.
Camera, include picture and video recording.

Progress is a bit slower than we expected. But we still are progressing nicely.

For app developers: it's now possible to build & test your apps against UTNext

After a long await, you can now start attempting to rebuild your app against Noble-based UTNext. This should allow you to test whether your app has any problem with the Noble-based images, especially if the app was unable to start on them before due to shared library changes.

For now, you'll need to get a nightly build of Clickable. After that, specify ubuntu-touch-next-internal as the framework inside clickable.yaml and specify policy_version of the AppArmor profile to 9999. You may also also have to make sure your manifest.json specifies @CLICK_FRAMEWORK@ in the framework field so that the correct version is filled in automatically by Clickable (sadly a similar mechanism doesn't exist yet for AppArmor policy - see this issue). When building, you'll have to specify --accept-review-errors for now, as click-reviewer-tools has not been updated.

ubuntu-touch-next-internal is a framework which corresponds to the on-going development of UTNext. The -internal part indicates that there is no formal "contract" for this framework. In other words, we don't guarantee forward- and backward- compatibility with any past and future Ubuntu Touch versions. The framework is intended for testing only and is not intended to be published to the Open Store; you'll have to switch to the final framework when it's available.

Due to delays and ongoing discussions, we at the core team are still unable to settle on what versioning scheme and what version number we will use for the next Ubuntu Touch release, and subsequently as the final framework name. We'll have a separated post discussing this in more details and allow you to chime in. We're sorry for this; as soon as we're able to finalize this detail, we'll provide an update to you.

Update: please see a separated post for a discussion around version number: https://forums.ubports.com/post/84517

For porters: it's now possible to drop touch.pa overlay ~~(for UTNext, at least)~~ now possible on both UTNext and 20.04

If your port is one of the port which has to overlay /etc/pulse/touch.pa to provide additional arguments to pulseaudio-module-droid-discover or pulseaudio-modules-droid-card-<API>, it's now possible to instead provide extra arguments using an Deviceinfo property. The property is called PulseaudioModulesDroid_ExtraCardArgs [1] and accept all arguments which you may add to pulseaudio-modules-droid-card-<API>. For example, you can put this in your Deviceinfo overlay to set sampling rate of your device's audio chip:

  PulseaudioModulesDroid_ExtraCardArgs: "rate=48000"

Combined with a change which allow you not to hard-code API level, it should now be possible to drop touch.pa overlay entirely. This feature is now merged into UTNext and 20.04, so you'll be able to share your device tarball between 20.04 and UTNext.

[1]: In case you're wondering, yes, there are PulseaudioModulesDroid_ExtraGlueArgs and PulseaudioModulesDroid_ExtraHidlArgs as well. However, I believe you won't need them.

@peat_psuwit
First test, i'm with clickable 8.2.0, got this while doing clickable build --arch=arm64 --accept-review-errors :

security:policy_groups_exists:utzip:utzip.apparmor
could not find policy groups
security:policy_version_exists:utzip.apparmor
could not find policy for ubuntu/9999.0
security:policy_version_matches_framework:utzip.apparmor
Invalid framework 'ubuntu-touch-next-internal'

I have checked the docker image, i'm on 24.04.
click-armor and ubuntu-sdk-libs seems old:
click-apparmor 0.5.1~20241107093457.7~2d4aff7+ubports~dev
ubuntu-sdk-libs 24.9+17+0~20250103234741.19+ubports~dev~1.gbp061821
