我时不时地会将 debian 卸载到本地目录中。直到 3 小时前它还运行良好，但是现在我收到此错误消息：
命令
debootstrap --include linux-image-4.9.0-3-amd64,sudo,openssh-server,hdparm,net-tools,udhcpc stretch /tmp/generate-image/mount
输出

直到几个小时前，输出是这样的：

... and so on
起初我以为这个包可能已经停产了。然而，运行后apt-get update，apt-cache search linux-image-4.9.0-3-amd64仍然找到这个包，所以它应该仍然可用。
上一个Debian 网站，它会[security]在包名称旁边打印一条红色通知。这是什么意思？难道是这个原因吗？我怎样才能继续debootstrap Debian？
答案1
现在稳定的内核是linux-image-4.9.0-4-amd64，您需要指定它。
更好的是，告诉debootstrap包含linux-image-amd64而不是特定版本，这样您将始终获得当前稳定的内核，并且不会遇到此类问题。
（旧包突然消失与Debian 9.2 发布今天。）
