在使用sudo apt-get install dconf-tools出现以下错误：
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_natty_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
可以使用以下命令解决：
sudo rm -vf /var/lib/apt/lists/*
sudo apt-get update
