속성 ethernet.mac-address이 잘못된 것 같습니다.
nmcli connection show "$PROFILE"또는 를 사용하여 프로필 내용을 확인하세요 nmcli -o connection show "$PROFILE". 여기서 "$PROFILE"은 입니다 'Wired connection 1'.
ethernet.mac-address그런 다음 적절한 값으로 조정합니다 . 아마도 설정을 해제하고 connection.interface-name대신 설정하면 됩니다.
nmcli connection modify "Wired connection 1" ethernet.mac-address '' connection.interface-name eno1.
그런 다음 를 사용하여 프로필을 다시 활성화하십시오 nmcli connection up Wired\ connection\ 1.
man nm-settings연결 프로필 속성의 의미는 을 참조하세요 .
