I'm able to ping us.archive.ubuntu.com just fine:

What can i do to fix this?

What I have tried so far.

I've tried following directions on this blog: http://nickescobedo.com/719/ubuntu-apt-get-hangs-at-0

To force apt-get to use IPv4 exclusively

  • Create a file in /etc/apt/apt.conf.d/99force-ipv4
  • Add this line to newly created file Acquire::ForceIPv4 false;
  • Apt-get will now use IPv4 exclusively

Best Answer

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
