请教大佬一个ubuntu运行dpkg的问题

我的vps是ubuntu系统，但无法安装dpkg，许多简单的系统升级命令都运行不了，都出现:

E: dpkg was interrupted, you must manually run \'dpkg --configure -a\' to correct the problem

它好像说是要运行dpkg --configure -a，但运行了dpkg --configure -a，又出现

dpkg: error: parsing file \'/var/lib/dpkg/updates/0001\' near line 0:

end of file after field name

请问怎么搞?
