我的问题看起来与这个相似- 但不，apt-get update对我没有任何帮助。

解决方案是确保软件源包含更新，如下所示：

$ sudo vi /etc/apt/sources.list
$ #add the following two lines to sources.list for raring-updates

 deb http://ch.archive.ubuntu.com/ubuntu/ raring main restricted
 deb-src http://ch.archive.ubuntu.com/ubuntu/ raring main restricted
+deb http://ch.archive.ubuntu.com/ubuntu/ raring-updates main restricted
+deb-src http://ch.archive.ubuntu.com/ubuntu/ raring-updates main restricted

$ sudo apt-get update
$ apt-cache policy libssl-dev

您应该会看到包含以下内容的输出 raring-updates

$ sudo apt-get install libssl-dev

这次应该工作！
