nmcli con up: "연결 활성화 실패: Wi-Fi 네트워크를 찾을 수 없습니다."

콘솔을 통해 알려진 네트워크에 연결하려고 합니다(나중에 이를 스크립트에 추가하겠습니다). 지금까지 가장 유망한 명령은 다음과 같습니다.

nmcli con up "Weelaan" ifname wlp4s0

최소한 WLAN 트레이 아이콘이 로딩 애니메이션으로 바뀌고 올바른 네트워크에 연결을 시도하는 것처럼 보이지만 잠시 후 오류 알림과 다음 출력이 표시됩니다.

Error: Connection activation failed: The Wi-Fi network could not be found
Hint: use 'journalctl -xe NM_CONNECTION=eef66f76-9566-4e3c-889c-9634960dd1b7 + NM_DEVICE=wlp4s0' to get more details.

프롬프트 명령을 실행하면 해당 시간에 다음 출력이 제공됩니다.

네트워크 트레이 아이콘을 클릭하고 네트워크의 "연결" 버튼을 클릭하기만 하면 됩니다. 하지만 해당 스크립트에서 마우스를 장악하고 싶지는 않습니다. 이는 또한 화면 해상도에 종속되게 만들고 다른 많은 바람직하지 않은 부작용을 갖게 됩니다. 그렇다면 nmcli문제는 무엇입니까? 이 문제를 어떻게 해결할 수 있나요? KDE의 네트워크 메뉴와 어떻게 다른가요?
