ubuntu 启动后停在ubuntu-logo画面或者进入到紫色底画面 有鼠标 没登陆器

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/ftp.osuosl.org_pub_ubuntu_dists_hardy_universe_binary-i386_Packages, E:The package lists or status file could not be parsed or opened.'

把所有源都清理一下，就留一个，加的ppa啥的都删掉。然后apt-get update，之后再运行升级。
