删除 PPA 导致 GPG 错误

Question

当我跑步时

sudo apt-get update

我收到以下错误：

W: GPG error: http://download.opensuse.org ./ Release: The following signatures were invalid: KEYEXPIRED 1436387333

如何找到并删除导致此错误的 PPA？

Answer 1

命令

grep -r 'download.opensuse.org' /etc/apt

显示配置存储库的位置，例如：

/etc/apt/sources.list.save:deb http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./ 
/etc/apt/sources.list.save:# deb-src http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./ 
/etc/apt/sources.list:deb http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./ 
/etc/apt/sources.list:# deb-src http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./

在你的情况下它是在

/etc/apt/sources.list

有了这些知识，您可以在以下命令的帮助下删除该条目sed

sudo sed -i '/download.opensuse.org/d' /etc/apt/sources.list

为了避免将来混淆，您还应该删除备份文件中的条目

sudo sed -i '/download.opensuse.org/d' /etc/apt/sources.list.save

现在更新包信息

sudo apt-get update

问题就解决了。
