I'm running Ubuntu 16.04
adb version
Android Debug Bridge version 1.0.32
However, when I plug in my devices for testing via ADB, I always get an unauthorized error.
adb devices
List of devices attached
LGD855a1098057 unauthorized
adb works flawlessly on Windows 7 x64 SP1 with Koushik Douttas Universal ADB driver and my friend's Macbook, this singles out the Ubuntu 16.04 as the problem.
Things I have tried:
I tried revoking previous USB authorizations: nothing happened.
Switching adb debugging on and off: however, the CLI just keeps telling me with the unauthorized error.
Switching ports: each port on my 16-port development rig has been tried.
Updating adb:
android-tools-adb is already the newest version (5.1.1r36+git20160322-0ubuntu3). android-tools-fastboot is already the newest version (5.1.1r36+git20160322-0ubuntu3).
