I am trying to install Cyanogenmod 13 in Oneplus 2 but I cannot get TWRP flashed in the phone because I cannot get adb work as expected with Ubuntu 16.04 in common Ubuntu, Persistent Live Ubuntu and Live Ubuntu.

1. Common Ubuntu

   
   
   

   The command adb devices and fastboot devices returns nothing, although it should not, since my Android phone is in the developer mode with enabled fastboot.
   Work flow

   masi@masi:~/Downloads$ sudo adb devices
   
   List of devices attached
   
   

   
   
   

   I think the adb version works at least in 14.04 but not now with 16.04.

   
   
   

   Inspecting with lsusb shows that the device is detected in Ubuntu as Bus 001 Device 050: ID 2a70:f003.

   
   
   

   Settings where I already authorized USB debugging

   
   
   

   

   
   
   

   I do when masi is in the group plugdev but still unsuccessful result

   
   
   

   # OrganicMarble
   
   sudo touch /etc/udev/rules.d/51-android.rules
   
   
   
   masi@masi:/$ sudo vim /etc/udev/rules.d/51-android.rules 
   
   
   
   masi@masi:~$ groups masi
   
   masi : masi adm cdrom sudo dip plugdev staff lpadmin sambashare
   
   
   
   masi@masi:/$ cat /etc/udev/rules.d/51-android.rules
   
   SUBSYSTEM=="usb", ATTR{idVendor}=="2a70", MODE="0666", GROUP="plugdev"
   
   
   
   masi@masi:/$ sudo chmod a+r /etc/udev/rules.d/51-android.rules
   
   
   
   masi@masi:/$ sudo adb devices
   
   * daemon not running. starting it now on port 5037 *
   
   * daemon started successfully *
   
   
   
   List of devices attached 
   
   
   
   masi@masi:/$ adb devices

2. Persistent Live Ubuntu

   
   
   

   Fails with bugs in /etc/hostname and /etc/hosts, not related to this case but reported here




3. Live Ubuntu 16.04

   
   
   

   This attempt fails in trying to get adb to work
