Bluetooth pairing problems Ubuntu 20.04: Failed to pair: org.bluez.Error.AuthenticationRejected

  • 772

Installed today Ubuntu 20.04 on my Laptop on a second partition. Unfortunately my Bluetooth suddenly stopped its service and won't connect to my Mouse and Keyboard. I tried this here and also tried to reinstall blueman. I tried to connect with the terminal and did these steps:

bluetoothctl
default-agent
pairable on
devices
trust CA:49:A5:2B:02:C4
pair CA:49:A5:2B:02:C4

I get this Error... Failed to pair: org.bluez.Error.AuthenticationRejected

Also if I want to access the Bluetooth Modul via the Bluetooth icon in the right corner next to the wifi icon. I get this error: blueman-assistant crashed with blueman.bluez.errors.DBusInProgressError in callback(): Operation already in progress

I hope you can help me and of course thank you very much in advance!

    I saw the same error with my new mouse. The steps mentioned here solved it for me.

    The solution is that within bluetoothctl, disconnect, untrust, and remove the device by bluetooth MAC address. Then, ensure your device is in pairing mode, scan and connect to the device.
