有时，当我安装东西时，我会收到如下错误：
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
package1 : Depends: package2 (>= 1.8) but 1.7.5-1ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.
我该如何解决这个问题？

multiarch-support is …我看到有些人有与/var/lib/dpkg/updates. 所有我能找到的目录是在它的文件编号0000，0001等和错误信息经常提到“文件的麻烦解析一个”。
/var/lib/dpkg/updates文件夹在我的系统上是空的，所以我看不到文件中的内容。我无法找到有关此目录中存储内容的信息，只有许多论坛帖子和错误报告提到了该目录。
那么，这个目录有什么用呢？
