无法运行任何apt-get更新而不杀死服务器

我有一个Ubuntu的12.04.2后,我试图对其进行升级而死亡。

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

所以我运行它,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. 

任何人以前见过这种行为?
