    Clear the cache of system settings app don't help.
    Switch to different channel like rc or dev brings up the same error.

    Installing via the installer i get the following error:

    error: Error: adb:format: Error: {"error":{"killed":false,"code":1,"signal":null,"cmd":"/opt/ubports-installer/resources/app.asar.unpacked/platform-tools/linux/adb -P 5037 shell echo ."},"stdout":"","stderr":"error: insufficient permissions for device: user in plugdev group; are your udev rules wrong?\nSee [http://developer.android.com/tools/device.html] for more information"}
