The candidate-channel-version of the
ubports-installer can now run in strict confinement. The UBports Installer is an electron-tool for installing Ubuntu Touch on supported Android devices. This is achieved by wrapping adb and fastboot (shipped in the package) and connecting them through the raw-usb interface.
Since the installer can not work without access to USB at all, we would really appreciate automatic connection. Without it, strict confinement is not really an option, as it undermines the idea that the user does not have to touch the terminal to install Ubuntu Touch.
