我正在尝试更新 Ubuntu 14.04 的软件，但出现错误：
malformed line /etc/apt/sources.list.d/virtualbox.list (dist) ; access to this source denied.
E:opening etc/apt/sources.list.d/virtualbox.list-ifstream::ifstream(13: Permission denied)
E: List of source could not be read
E:The package lists or status file could not be parsed or opened.
你能帮我删除这个virtualbox.list吗？
我真的很感谢你的帮助。
