I recently installed ubuntu 22.04 LTS and my earphone will not connect. bluetooth is working as it can show my devices but it will not connect.
I have tried reinstalling the bluez package and also tried restarting the bluetooth service multiple time
my bluetooth is working fine in windows and it was also working fine in Ubuntu 24.04
here is the output of systemctl status bluetooth
