My logi MX Keys Mini keyboard has been working well for a year or so and suddenly started disconnecting from Bluetooth. I can pair it but it disconnects within 5 seconds.
The message I get from journalctl -u bluetooth | tail is:
bluetoothd[6671]: src/device.c:load_gatt_db() No cache for DE:BC:97:80:A4:1C
BLuetoothctl shows the error
[CHG] Device DE:BC:97:80:A4:1C Connected: no Failed to pair: org.bluez.Error.AuthenticationCanceled
I tried removing the keyboard, clearing the bluetooth cache and using previous kernel version but nothing works. Also tried with a different keyboard and the same keeps happening. I'm on Ubuntu 22.04.4 LTS, kernel 6.5.0-21.
Does anyone have any clue what else I could try?
