我现在应该怎么做？？？：（
答案1
我在 Debian 测试、不稳定、实验性和 wheezy-backports 中看到了该软件包。所以我猜你正在使用 Debian stable，别名“Wheezy”。 （检查输出以apt-cache policy确定，或将其发布在这里。）
如果是这种情况，您应该简单地将 Wheezy-backports 添加到您的源中：添加一行
deb http://ftp.de.debian.org/debian/ wheezy-backports main non-free contrib
要么或更好地创建一个仅包含该行的/etc/apt/sources.list新文件。/etc/apt/sources.list.d/wheezy-backports.list然后运行apt-get update，你应该准备好了......
