ubuntu 18.04 java安装问题

ubuntu 18.04 java安装问题

每次我尝试使用以下命令在 Ubuntu 18.04(在 VirtualBox VM 上)上安装 java(我已经尝试了其他主题/论坛中的其他几个命令/方法):

sudo apt install default-jdk

无论我做什么,当需要检索标头时,我都会收到以下错误:

似乎无法连接到这些存储库,或者它们不再可用。

抱歉,但是,只是为了检查一下。您可以在此 VirtualBox 操作系统中访问互联网吗?然后,了解如何更改 Ubuntu 18.04 的存储库源。

我没有准确回答,因为我已经很长时间没有使用Ubuntu了,但我发现了这个:
