Hello,
I've installed with the installer 0.9.7-beta the stable/rc and devel version on my pixel3a and I've some errors with apparmor. For each version I've wipe data

Am I the only one with this problem ?

Hi,
I use UBports RC release with my pixel3a and when I start application with a custom WebEngineProfile as uteezer https://github.com/Tafitson/uteezer/blob/main/app/Main.qml apparmor denied access.

Hello I've buy a vollaphone with ubuntu touch.I would test droidian but that didin't works with latest ubports-installer.

• Installation droidian with latest release

The installer download files and when it should rebooting to bootloader but Ubuntu touch restarts and the installation don't begin.

Same thing with Ubuntu or Windows
