我正在使用 Ubuntu Server。
当我做：
apt-get 升级
它卡在了：
设置 openjdk-6-jre-headless (6b20-1.9.7-0ubuntu1) ...
为什么？我该怎么做才能阻止它？
我尝试使用 apt-get 将其删除...但出现此错误：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
因此我尝试了这个：
dpkg --purge openjdk-6-jre-headless
我懂了：
dpkg: dependency problems prevent removal of openjdk-6-jre-headless:
openjdk-6-jre-lib depends on openjdk-6-jre-headless (>= 6b17).
ca-certificates-java depends on openjdk-6-jre-headless (>= 6b16-1.6.1-2) | java6-runtime-headless; however:

问题是我认为我的数据库正在使用它...不确定...我正在将 Cassandra 与 Thrift 一起使用...
是的，它变得有点复杂...
# dpkg --configure -a
我得到：

再次感谢任何帮助。
答案1
我以前很少遇到类似这样的升级问题。
两种可能性，尝试一下：
apt-get update
然后
apt-get upgrade
失败的话，尝试
apt-get remove openjdk-6-jre-headless
然后
apt-get upgrade
然后
apt-get install openjdk-6-jre-headless
答案2
Cassandra 是一个 Java 应用程序，根据您运行的版本，它需要不同的 Java 包。过去它需要 openjdk，但我相信新版本将接受 sunJDK。您必须拥有其中一个才能使其工作。
答案3
dpkg -C将审核您的系统中是否存在配置错误或不起作用的软件包，然后推荐解决方案。
您也应该尝试手动删除依赖树的顶部：您是否尝试过删除ca-certificates-java？如果删除失败，您可以删除它的依赖者，依此类推。
作为最后的手段：如果您dpkg使用该--force-depends标志运行，所有依赖性错误都会自动变成警告。当然，这允许您破坏系统；请谨慎使用。当然，首先包含该--dry-run选项以检查所做的事情是否是您想要的。
