Update Ubuntu Touch apps to 20.04 Focal Fossa

[Beta Break]

This is the instruction shared to update your Ubuntu Touch apps to 20.04 Focal Fossa:

Modify manifest.json with "architecture":

@CLICK_ARCH@

Rename all imports:

find -name '*.qml' | xargs -I {} sed -i 's/import Ubuntu\./import Lomiri./g' {}

( there could be also some names to rename: e.g (UbuntuNumberAnimation, UbuntuColors , UbuntuShape)

clickable clean

Run clickable with 20.04 context:

CLICKABLE_FRAMEWORK=ubuntu-sdk-20.04 clickable...

Please reply when you have additional suggestions, or when you find bugs. Thanks!

@remark I would suggest to use the CLICKABLE_FRAMEWORK env var only when building for xenial and focal from the exact same code base, using the QML compat layer. As the instructions suggest to replace Ubuntu imports by Lomiri, I'd rather suggest to set framework: ubuntu-sdk-20.04 in the clickable.yaml.

@jonius Is it required in clickable.yaml or changing the framework in the manifest works? I guess not since the clickable config let's it identify that it's focal?

[kugiigi]

These are the things I've done in my apps:

1. Set framework in clickable config file
   "framework": "ubuntu-sdk-20.04"
2. Set framework in manifest
   "framework": "ubuntu-sdk-20.04"
3. Update policy in the apparmor config
   "policy_version": 20.04
4. Run the following inside the project's directory

   find -name '*.qml' | xargs -I {} sed -i 's/import Ubuntu\./import Lomiri./g' {}
   find -name '*.qml' | xargs -I {} sed -i 's/UbuntuAnimation/LomiriAnimation/g' {}
   find -name '*.qml' | xargs -I {} sed -i 's/UbuntuNumberAnimation/LomiriNumberAnimation/g' {}
   find -name '*.qml' | xargs -I {} sed -i 's/UbuntuListView/LomiriListView/g' {}
   find -name '*.qml' | xargs -I {} sed -i 's/UbuntuColors/LomiriColors/g' {}
   find -name '*.qml' | xargs -I {} sed -i 's/UbuntuShape/LomiriShape/g' {}
   

Also, tailing app logs since Logviewer isn't updated yet for focal
journalctl -f --user-unit lomiri-app-launch--application-click--<appname>

@kugiigi Clickable does not consider the manifest when deciding to use a xenial/focal docker image. It considers the framework in the project config or the env var. Otherwise it uses its default, which still is xenial. For a QML only app (after testing it really works in focal), one could keep the 16.04 framework for now and just upload the same click for focal.

Note that clickable log and clickable logs use journalctl for focal (if the framework is specified as focal).

The instructions above should be updated with what you suggest. :thumbs_up:

[jonius]

What is also missing is updating the app armor policy to 20.04 and renaming the X-Ubuntu keys in the desktop file to X-Lomiri.

To add a few lines to @kugiigi s post with the replace work that needs doing, here my addition of a few more lines:

find -name '*.qml' | xargs -I {} sed -i 's/Ubuntu.Components/Lomiri.Components/g' {}
find -name '*.qml' | xargs -I {} sed -i 's/Ubuntu.Connectivity/Lomiri.Connectivity/g' {}
find -name '*.in.in' | xargs -I {} sed -i 's/X-Ubuntu/X-Lomiri/g' {}

The last line is for the desktop file.

[kugiigi]

@danfro First 2 lines might already be covered by the replace for import Ubuntu

[danfro]

@kugiigi true. I wonder why I noted those lines a while ago.
