我尝试更新我的系统（12.04 LTA 64 位，在 ACER aspire V5 上）得到了这个：

无法初始化包信息

初始化包信息时出现无法解决的问题。

请针对“update-manager”包报告此错误，并包含以下错误消息：

E:Encountered a section with no Package: header,
E:Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_precise-security_main_binary-i386_Packages,
E:The package lists or status file could not be parsed or opened.

Run Code Online (Sandbox Code Playgroud)

怎么办？

这样做时，sudo apt-get upgrade我收到此错误。拜托，谁能帮我摆脱这个错误...
