无法移除ppa

Question

我最近在我的软件源代码中添加了stormcloud (ppa:jolicloud-team/ppa)，但它恰好是一个空源，每当我试图安装stormcloud或更新我的系统时，它都会出现一个错误。例如：

W: Failed to fetch http://ppa.launchpad.net/cooperjona/stormcloud/ubuntu/dists/precise/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/cooperjona/stormcloud/ubuntu/dists/precise/main/binary-i386/Packages  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

我无法删除这个ppa --我无法在/etc/apt/ unable .列表中找到它，也不能将它从命令行中移除。例如，当我这样做时：

sudo add-apt-repository --remove ppa:cooperjona/stormcloud

它会给出以下错误。

Cannot access PPA (https://launchpad.net/api/1.0/~cooperjona/+archive/stormcloud) to get PPA information, please check your internet connection.

当我使用ppa-清除时，我得到了以下结果-结果我流产了。

$ sudo ppa-purge ppa:jolicloud-team/ppa

这并没有损害我的电脑或其他东西，但根据我过去的经验，我已经吸取了一两次关于ppas故障的教训，我不希望我的软件包完全崩溃。我该怎么办？

(我使用的是Ubuntu12.04 LTS)

我相信，如果你进入终端的折叠命令，你可以把他们从那里移除。

software-properties-gtk --open-tab=2

或系统Settings>软件和更新。接下来点击第二个选项卡进入其他软件。

选择不想检查的源(空的)，或者关闭滴答，或者一起删除。
