点击 software up to date 提示：
Could not initialize the package information

An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/cn.archive.ubuntu.com_ubuntu_dists_precise-updates_main_i18n_Translation-en, E:The package lists or status file could not be parsed or opened.'

原因可能是我尝试在 system setting 中运行Management Service。
运行时提示 需要安装 landscape，但是安装失败。

经过检查发现是因为安装了32位的linuxqq的原因，删除之后恢复正常。
