当我尝试使用 apt update 进行更新时,出现以下错误。

事实上,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。
我还尝试在更新时强制使用 IPV4,以查看是否是 IPV6 问题。我还尝试删除所有这些 ppa,然后再次添加它们。
答案1
当我遇到这种情况时(有时没有网络变化),我发现使用apt-get
而不是apt
有效。
答案2
好吧,现在我连接到大学宿舍的网络时,问题解决了。可能是 ISP 或路由器出了问题。
更新:
好的,我确实发现了这个问题,我认为最好将它添加到这里的讨论中,以便其他人可能会发现它有用。
问题是我家的互联网调制解调器没有启用 ipv6。所以我进入调制解调器配置 ip 地址并启用它,我家的问题也解决了。
您的 ISP 也可能不支持 IPv6,印度的 BSNL 就是这种情况,因此也要注意这一点。
