如果不关闭服务器，就无法运行任何 apt-get 更新

Question

我有一个 ubuntu 12.04.2，在我尝试对其进行升级后它就死机了。

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

因此我运行它并得到以下输出。

Processing triggers for initramfs-tools ...
update-initramfs: Generating /boot/initrd.img-3.2.0-29-virtual
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place
Setting up openjdk-6-jre-headless (6b27-1.12.3-0ubuntu1~12.04) ...
Connection to ec2-xx-xx-xx-xx.compute-1.amazonaws.com closed.

以前有人见过这种行为吗？
