After I updated Ubuntu from 20.04 to 22.04, my system cannot connect to my Huawei Freebuds 3 bluetooth headphones anymore. When I click on the headphones in the devices list, it tries to connect for a while, until it stops. I already removed the device and tried to pair again, but with the same result.
I tried to establish an connection on the command-line via bluetoothctl as described in this blog article, but the result is the same, and it doesn't report any error. Is there a command-line tool for bluetooth that actually outputs a useful log/error message?
Furthermore, I tried this suggestion, but after re-installing pulseaudio-module-bluetooth, sudo pactl https://askubuntu.com/a/1369477/515475 reports the error
