今天我收到了更新通知，其中一些是 libapt。
因此我按下“安装更新”，但出现此错误：
以下软件包具有未满足的依赖关系：
libapt-inst1.4:i386: Depends: libapt-pkg4.12 (>= 0.8.16~exp12ubuntu10.2) but 0.8.16~exp12ubuntu10.3 is installed
Depends: libc6 (>= 2.4) but 2.15-0ubuntu10 is installed
Depends: libgcc1 (>= 1:4.1.1) but 1:4.6.3-1ubuntu5 is installed
Depends: libstdc++6 (>= 4.4.0) but 4.6.3-1ubuntu5 is installed
于是我打开终端并输入，sudo apt-get install -f
结果显示：
The following extra packages will be installed:
libapt-inst1.4 libapt-inst1.4:i386 libapt-pkg4.12:i386
The following NEW packages will be installed:
libapt-pkg4.12:i386
The following packages will be upgraded:

Need to get 0 B/1,146 kB of archives.

Do you want to continue [Y/n]?
我选择了“是”。
进而：
E: Internal Error, No file name for libapt-pkg4.12
另外，当我打开软件中心时，我收到数据库已损坏的消息......
我使用的是 12.04 64 位
但是为什么它要安装 i386 版本？我正在使用 64 位 ubuntu...
