I cannot pair a Logitech K380 keyboard to a Raspberry Pi 4B with 4GB RAM in Ubuntu MATE 20.04.
I can "connect" but I cannot "pair". I have paired successfully with this hardware combination using Raspberry Pi OS. I would like for the pairing to persist through a restart so that I do not have to manually reconnect/re-pair after a reboot or when waking the machine from sleep.
The problem Is that bluetooth does not display a dialog that specifies a PIN code for pairing.
Does anyone have ideas on how to resolve this issue?
