从 Debian Stable (Buster) 成功安装 DDD 调试器时遇到问题
当我尝试安装 ddd 时，它无法安装并出现错误：
robert@pip2:/tmp$ sudo -l
[sudo] password for robert:

我是通过 netinst 安装的，没有任何自定义，只是默认的桌面安装。
不确定要对sources.list 进行哪些调整，因为这是我第一次在安装软件包时遇到问题。
我的 /etc/apt/sources.list 文件：
robert@pip2:/etc/apt$ cat ./sources.list

“请将输出添加apt-get update到问题中。”
这里是：
robert@pip2:/tmp$ sudo apt-get update
