无法升级包，它会卡在openjdk-6-jre-headless上
我正在使用Ubuntu Maverick（服务器）。
当我跑：
apt-get upgrade 它被困在：
Setting up 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删除它但得到此错误：
E：dpkg被中断，你必须手动运行’sudo dpkg –configure -a’来解决问题。
那么我试过这个：
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: Package openjdk-6-jre-headless is to be removed.

问题是我认为我的数据库正在使用它……不确定……我正在使用Cassandra和Thrift ……
是的，它变得有点复杂……
# dpkg --configure -a
我明白了：
dpkg: dependency problems prevent configuration of openjdk-6-jre: openjdk-6-jre depends on openjdk-6-jre-headless (>= 6b20-1.9.7-0ubuntu1); however: Package openjdk-6-jre-headless is not configured yet. dpkg: error processing openjdk-6-jre (--configure): dependency problems - leaving unconfigured Processing triggers for libc-bin ... ldconfig deferred processing now taking place dpkg: dependency problems prevent configuration of libaccess-bridge-java: libaccess-bridge-java depends on default-jre | openjdk-6-jre | sun-java6-jre; however: Package default-jre is not installed.

再次感谢任何帮助。
这实际上是EC2上t1.micro实例的一个众所周知的错误

请注意，这在US-WEST-2中已得到修复：

好吧，我知道这是一个老问题，但我在一个系统上遇到过它（显然没有修补一段时间），我终于得到了它：
dpkg --force-all -P openjdk-6-jre-headless apt-get update apt-get -f install
（ --force-all很重要）之后，我可以升级系统
