为什么 apt-get 会自行中止，就好像我按下了“N”？

Question

在 Ubuntu 14.04 上，当我尝试安装应用程序甚至只是执行以下操作时：

sudo apt-get upgrade

我总是在最后得到这条消息：

Do you want to continue? [Y/n] Abort.

我没有输入任何内容，它只是自动中止。

你们能帮帮我吗？

========[ 编辑 #1 8 月 12 日]======== 这里我复制了整个终端文本。我在这里运行了 2 个命令，即： sudo apt-get update 然后在我得到结果后运行 sudo apt-get upgrade

这是从终端复制的文本：

Answer 1

apt-get 在需要交互式确认但无法从标准输入读取输入时中止。

例如，任何人（有待升级）都可以通过将 /dev/null 重定向到 stdin 来重现此行为：

skath@tahiti:~$ sudo apt-get upgrade < /dev/null

Need to get 29.3 kB of archives.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n] Abort.
skath@tahiti:~$

这就引出了下一个问题，当你打电话时，什么接管了标准输入sudo apt-get upgrade？这是一个棘手的问题，可能涉及您的 sudo 配置或您用来调用命令的终端或 shell...

或者，如果你只需要一个解决方法，您可以传递-y到apt-get跳过提示：sudo apt-get -y upgrade

Answer 2

我的问题是我试图通过将它们复制粘贴到控制台来一次运行多个命令

apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get install build-essential
...

分别调用每个命令解决了我的问题
