Bug description:
  Hi everyone, I've installed ubuntu 20.04 one week ago for the first time and 
I'm not expert. I have some issue with my bluetooth adapter: from 
settings/bluetooth it can find other bluetooth devices, but cannot pair with 
them. The adapter isn't shown typing *dmesg | grep -i blue* or typing *dmesg | 
grep -i blue*
  I'm shure I have a bluetooth adapter because it was working on windows.

  Typing *sudo cat /sys/kernel/debug/usb/devices* this is shown:

[Kernel-packages] [Bug 1885422] Re: Intel Wireless 8265 / 8275 [8086:24fd] Subsystem [8086:1014] Bluetooth doesn't pair with other devices

2020-06-28 Thread You-Sheng Yang
Hi, could you run btmon to dump bluetooth traffic data while trying to
pair with other devices?

  1. Run `sudo btmon -w btsnoop.log` in a terminal,

  2. Open GNOME Settings to scan devices and try to pair one of them,

  3. When failed, terminate btmon by Ctrl+C and attach that log file
here.
