add-apt-respository 总是超时

我正在尝试添加 ppa 来在我的 ubuntu 机器上安装 i3 gaps，但是 add-apt-respository 每次都会超时。

我该怎么做才能解决这个问题？我尝试了几个不同的存储库来获取我需要的包，但还是发生了同样的事情。

答案1

对我来说，这是计算机在未设置 IPv6 时尝试使用 IPv6 进行连接时出现的问题。

运行以下命令禁用 IPv6，然后重试，对我来说有效。

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

答案2

尝试使用以下命令 ping PPA 服务器：

ping ppa.launchpadcontent.net

作为参考，此 DNS 记录是2022 年宣布。

如果您的机器无法连接 PPA 服务器，该add-apt-respository命令将显示无响应或最终超时。

这可能是由防火墙、DNS 问题或任何其他网络问题引起的。
