如何从更新中找到要删除的PPA？

Question

当我运行apt-get更新时，我会在最后得到一些失败，我想删除它们，但是我不知道它们来自哪个PPA。我已经安装了Y管理器，但仍然找不到它的来源.

Answer 1

我认为你应该能够使用GUI‘软件和更新’的程序。默认情况下是安装的。使用下面的说明

1. 打开“软件和更新”，从Dash搜索它。
2. 打开“其他软件”选项卡。
3. 找到与给您带来问题的存储库相关的任何行(本例中为Medibuntu)，并取消它前面的框。请注意，它们的标题可能是完整的URL或更友好的名称。
4. 关上窗户
5. 重新运行并检查是否仍有错误，如果仍然错误，请尝试禁用更多相关的repos。sudo apt-get update

Answer 2

所有的中期回复都不起作用，所以这会找到它们的位置

grep -RE '^\s*[^#].*medibuntu.*' /etc/apt/sources.list{,.d/*.list}

可能只会显示几个文件。编辑这些代码(删除这些行或用#注释它们)，您的下一个更新应该工作得很好。
