There's a situation that's stuck in that way.

Turns out a issue where connecting over IPV6 in 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

Remove

precedence ::ffff:0:0/96 100

This would allow you to still with IPV6 but sets IPv4 as the precedence so that Apt-get won ' t get stuck.
