I am trying to pair my JBL earbuds to my pc on Ubuntu 20.04 LTS. I have got 3 exactly same pc, these 3 are exactly same model same brand. When i try to connect my earbud to these two pc, there is no problem. But the other one gives error as below:
[bluetooth]# pair 78:5E:A2:75:00:89
Attempting to pair with 78:5E:A2:75:00:89
Failed to pair: org.bluez.Error.ConnectionAttemptFailed
[bluetooth]# connect 78:5E:A2:75:00:89
Attempting to connect to 78:5E:A2:75:00:89
Failed to connect: org.bluez.Error.Failed
And when i open the log file /var/log/syslog file is as below, i dont know which part is unnecessary so i just copy the all area related with my device's mac address :

Sometimes it just connects with one try but 90% it does not. I tried to restart pulseaudio. Problem still occurs. I cant pair my earbud to pc.
