如果我尝试更新我的 Linux Ubuntu 12.04 LTS，我会收到以下消息：
Could not initialise the package information
An unresolvable problem occurred while initialising the package information.
Please report this bug for the 'update-manager' package and try to include the following error message:
'E:Malformed line 5 in source list /etc/apt/sources.list (dist parse)'
我怎么解决这个问题？

您可以通过撤消对 sources.list 所做的更改（这会破坏文件）来解决这个问题。如果您不确定要更改什么，请将整个文件添加到您的问题中（不要将其作为评论发布）。
在 sources.list 共享后进行编辑：
您需要删除那些虚假的 mozilla.org 行，它们毫无意义。
