apt-get error ubuntu

I got one error with “apt-get” command in one of our server which has Ubuntu 12.04 OS. After the Y/N confirmation of apt-get installation command the server went to un-responded state for 4-6 minutes.

Error details are pasted below:

0% [Connecting to archive.ubuntu.com(2001:67c:1360:8c01::1a)]


I figured out the problem. I had to disable IPv6 connectivity, as The Lord Of Time pointed out.
Running the following command in Terminal tells if IPv6 is enabled or not:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
0 means its enabled
1 means its disabled

To disable IPv6 from within Terminal, enter the following and reboot:

echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf

After boot, re-run the first command(cat /proc/sys/net/ipv6/conf/all/disable_ipv6), and it should be 1 now.

You may use the below pasted command to disable IPv6 connectivity.

echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

That’s it 🙂

Introduction to IAAC [Infrastructure As A Code] tools

It’s time that I had to write an article on IAAC. All giant’s infra are now set and manage as IAAC. Infrastructure As A Code is shorted as IAAC.

I hope you guys are already aware of these tools and you are already started working on that. This is a simple, straight intro to those tools. This will help you to start your journey as an automation engineer.
