Ec2 instance on AWS apt- get not working

Question

I have Ec2 instance on AWS with Amazon Ubuntu.

When i try to download any thing, I am unable to do so.

For Ex:

~# apt-get update

0% [Connect         


        

Answer 1

I figured out how to get apt-get to work again.

Edit gai.conf:

sudo vim /etc/gai.conf

change line ~54 to uncomment the following:

precedence ::ffff:0:0/96 100

write and quit:

:wq

CAUTION

Look out line 50 which looks almost identical:

precedence ::ffff:0:0/96 10

This is the wrong line. Go ~4 lines down and you'll find the correct line to uncomment because it ends with 100 instead of 10
