Airpods를 페어링할 때 Bluez가 인증에서 멈춤

LED 표시등이 흰색으로 바뀌고 깜박일 때까지 에어팟 버튼을 누른 후

[bluetooth]# pair <mac-address>

반품

Attempting to pair with 18:F1:D8:36:53:FB

하지만 에어팟의 LED가 다시 녹색으로 바뀔 때까지 오랜 시간 동안 그대로 유지되며 다음 오류가 발생합니다.

Failed to pair: org.bluez.Error.AuthenticationCanceled

이로 인해 인증 단계에서 정체된 것으로 보입니다.

내 에어팟은 다른 우분투 컴퓨터와 안드로이드 휴대폰에 페어링할 수 있으므로 이것이 이 컴퓨터의 블루투스 설정에 문제가 있는 것 같습니다.
