我正在使用 Ubuntu 14.04。我已经完成了以下操作来禁用ipv6。
我已经打开/etc/sysctl.conf使用gedit并将以下几行粘贴到sysctl.conf.
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
但是当我使用以下命令检查它时，
$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
I am getting result as '0'( i.e still Enabled). Please help me to disable ipv6, so that I can use hadoop.
I followed instructions from this link.
我目前正在使用 Ubuntu 16.04 Beta 2，每次我尝试通过sudo apt-get update或升级槽在家更新时，sudo apt-get upgrade我都不会得到任何反馈。即使安装任何东西都会有相同的结果。它只会“挂断” 0% while fetching data。
$ sudo apt-get update

我不知道如何解决这个问题。我已经尝试过ping6 archive.ubuntu.com100% 丢包，而只是 ping 不会有任何丢失。
我也将 DNS 服务器（IPv4 和 IPv6）更改为 Google 的无解决方案。
