问题是我可以从我的网络浏览器访问这些链接,所以这一定不是服务器的问题。

我曾尝试仅在更新时强制使用 IPV4,以查看其是否存在 IPV6 问题。我也尝试删除所有这些ppas并再次添加它们。

当我遇到这种情况时(偶尔没有网络更改),我发现使用而apt-get不是apt有效。

好的,现在解决了,当我在我的大学宿舍连接到网络时。可能是 ISP 或路由器的一些问题。

更新:

好的,我实际上发现了这个问题,我认为将它添加到这里的讨论中会很好,这样其他人可能会觉得它有帮助。

问题是我的家庭互联网调制解调器没有启用 ipv6。所以我去了调制解调器配置IP地址并启用它,问题在我家也得到了解决。

也可能是您的 ISP 不支持 ipv6,印度的 BSNL 就是这种情况,所以也要注意这一点。
