Reading package lists... Error!

E: Encountered a section with no Package: header

E: Problem with MergeList /var/lib/apt/lists/AZ.archive.ubuntu.com_ubuntu_dists_natty_main_i18n _Translation-en

E: The package lists or status file could not be parsed or opened.

遇到該問題一般是Ubuntu安裝源的問題，需要輸入以下2個命令：

1sudo rm /var/lib/apt/lists/* -vf

2sudo apt-get update

具體解決：

run these two commands and it should get you fixed up.

Code:

sudo rm /var/lib/apt/lists/* -vf

The first command will remove the damaged list and when you run the second command it will replace it with a new list.

Code:

sudo apt-get update
