Ubuntu 21.04 中配对蓝牙设备失败

我发现配对蓝牙设备失败很常见。我有 Ubuntu 21.04，我插入了一个蓝牙 4.0 适配器，设备（耳机）可见但未获得配对。我检查了蓝牙的状态，它似乎正在运行：

sudo service bluetooth status
● bluetooth.service - Bluetooth service
     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor pre>
     Active: active (running) since Mon 2021-09-27 09:54:30 CEST; 57min ago

我错过了什么？

谢谢
