<![CDATA[adb shell not working Meizu Pro 5]]>Hi all, any idea why adb shell won't work on Meizu Pro 5? It worked before on Canonical image without any problem, now is showing me this:

adb shell
error: device unauthorized. Please check the confirmation dialog on your device.
And no dialog on phone, nothing
Tried to adb kill-server and adb start-server, tried to reboot phone or PC,
still the same. Also tried to change the fingerprint authentication for password only numbers, but nothing. Am I missing something?

There used to be a message on the phone about RSA keys when first connected to a PC, after a fresh install, but not anymore. (Canonical image)

It works great. I can also do 'adb shell' The only trick is that first time after you switch dev mode it asks to allow computer to connect on the phone. You have to accept message on the phone. After that you can connect with adb shell.
Thanks for great new system!

Developer mode on, but the same error: device unauthorized. No confirmation dialog on device. Using UBports 15.04 stable

I'm short on suggestions, but i think i have read that authentication is optional so it could be worth trying to find it and turn it off.

Do you have another PC that you can try, or a different OS to boot on the same PC? Do you have any other Ubuntu phone that you could try the adb shell on with this same PC?
