修复Cockpit面板 cannot refresh cache whilst offline 报错

系统 Ubuntu 20.04.3 LTS

安装cockpit后, 软件列表刷新一直报错, 提示cannot refresh cache whilst offline.

解决方法: 在netplan中调整渲染器(renderer)为NetworkManager, ubuntu默认的渲染器为networkd. 配置类似如下:

network:
  ethernets:
    ens18:
      dhcp4: true
  version: 2
  renderer: NetworkManager
