Ubuntu 16.04-无法运行软件更新或 apt-get-update

我正在运行 Ubuntu 16.04。几个月来我一直无法更新软件，因为我一直收到此消息。我尝试在服务器之间切换。但问题不大。尝试更新过期的密钥。仍然没有成功。请帮我解决这个问题。我甚至无法升级到较新版本的 Ubuntu 来修复它。什么都不起作用。

我还想知道这是否与软件更新中的“信任软件提供商”部分为空有关。以下是屏幕截图： 在此处输入图片描述

软件更新程序为我提供以下信息：

无法下载存储库信息。请检查您的互联网连接。

无法运行sudo-apt-get-update。我收到此消息：

然后我尝试更新密钥：

for K in $(apt-key list | grep expired | cut -d '/' -f2 | cut -d' '-f1); do sudo apt-key adv --recv-keys --keyserver keys.gnupg.net $K; done

并输出：

答案1

您的 opensuse 存储库的 GPG 密钥已过期。

如果您不需要此源，请使用以下命令注释源条目：

sudo sed -i '/opensuse/ s/^/#/' /etc/apt/sources.list.d/*.list

并运行此命令删除过期的密钥：

sudo apt-key del 1496576244

然后运行此命令来更新存储库：

sudo apt update
