報錯原因：未聯網，網絡連接設置為了橋接模式，需要把其改為NAT模式，共享主機的IP地址。

 

附上修改方法：

虛擬機安裝ubuntu上網的設置方法，分為主機有線上網和無線上網。

一、有線上網。

1. 首先完全關閉ubuntu。

2. 打開虛擬機，找到unbutu，右鍵“設置”，如圖所示。

   

3. 然后點“網絡適配器”，如圖所示。

   

4. 如果沒有設置過，默認的是NAT，點擊確定即可。

二、主機無線上網。

1. 同樣是首先完全關閉ubuntu。

2. 還是找到unbutu，右鍵“設置”找到“網絡適配器”，如圖所示。

   

3. 然后勾選“橋接模式”確定即可，如圖所示。

   

4. 最后打開ubuntu，已經可以上網了。
