出現這種一直卡在那得狀況解決辦法

Turns out this is an issue where connecting over IPv6 on some servers causes them to get stuck at this point. The fix is really simple.

Open /etc/gai.conf

Uncomment the following line:

#
# For sites which prefer IPv4 connections change the last line to
# precedence ::ffff:0:0/96 100

去掉#

precedence ::ffff:0:0/96 100

This will allow you to still use IPv6 but sets IPv4 as the precedence so that apt-get won’t get stuck.
