ubuntu12.04 无法更新，老是提示系统出问题，更新缓存失败E:Encountered a section with no Package: header....

我用的ubuntu12.04 一直用的好好的，直到有一天桌面右上角出现一道横线，无法检查更新，提示E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/cn.archive.ubuntu.com_ubuntu_dists_natty_main_binary-i386_Packages

于是便googel起来，记录下来以便今后查阅
