최근 업그레이드 후 network-manager-gnome을 제거했거나 upgrade -f를 수행 한 것으로 보이므로 패널에 네트워크 표시기가 보이지 않습니다. 무선 및 로컬 네트워크가 활성화되어 있습니다.

나는 시도했다 :

1. nm-applet, 설치되지 않았습니다 . network-manager-gnome을 설치하여 설치하려고하면 다음과 같은 메시지가 나타납니다.

   The following packages have unmet dependencies:
   network-manager-gnome : Depends: default-dbus-session-bus but it is not installable or dbus-session-bus but it is not installable
                           Recommends: mobile-broadband-provider-info but it is not going to be installed
   E: Unable to correct problems, you have held broken packages.
   

2. 서비스 sudo service network-manager restart를 다시 시작 하면 서비스 가 다시 시작되어 다시 작동하지만 표시기는 없습니다.
