    The problem seems to be different on this question that the one suggested as duplicate by @SOORAJS. Just for consideration before closing it is desirable to provide a better previous answer or a new one to keep this question active. Thank you. – Geppettvs D'Constanzo Mar 16 '15 at 07:13

    @DavidFoerster, My problem is some what similar to that problem, but that suggestion did,t help me and since I don't have 50 score so I can't put comments in that post too. Hoping for your help. – kumarhimanshu449 Mar 17 '15 at 08:00

    Ok. Does host extras.ubuntu.com resolve to an IP address? If not, try host extras.ubuntu.com 8.8.8.8. – David Foerster Mar 17 '15 at 11:19
  • Did you solved it? – 0x2b3bfa0 Mar 17 '15 at 12:32
  • Thanks @DavidFoerster and Helio for your valuable help. I was facing "No address associated with hostname" error with three hosts (extras.ubuntu.com, in.archive.ubuntu.com and security.ubuntu.com). I first find out the IP address as suggested by David (host extras.ubuntu.com 8.8.8.8), than I updated my "/etc/host" file as suggested by Helio (sudo nano /etc/host). Now command “sudo apt-get update” is working very fine without any error. Thanks once more to both of you :) – kumarhimanshu449 Mar 17 '15 at 12:58
  • Can you update the post with your new /etc/hosts file? – 0x2b3bfa0 Mar 17 '15 at 13:06

  • @Helio, Actually I am trying to install a software in ubuntu name Ambari [http://docs.hortonworks.com/HDPDocuments/Ambari-1.7.0.0/AMBARI_DOC_SUITE/index.html#Item2.5.3]. During the process of installing this software I created public and private SSH keys using command 'ssh-keygen'. Is it possible due to this I am again facing problem in update command? – kumarhimanshu449 Mar 18 '15 at 12:30
  • @DavidFoerster, Now when I am using 'host extras.ubuntu.com 8.8.8.8' to get the ipaddress it is showing ';; connection timed out; no servers could be reached'. – kumarhimanshu449 Mar 18 '15 at 12:32
  • Looks like you can't reach Google's DNS server. Does your internet connection work otherwise? As a last resort try ping 8.8.8.8. – David Foerster Mar 18 '15 at 12:47
  • I tried 'ping 8.8.8.8', it's not pinging. it shows --- 8.8.8.8 ping statistics --- 882 packets transmitted, 0 received, 100% packet loss, time 888046ms – kumarhimanshu449 Mar 18 '15 at 13:41

It may be a well-known bug in apt-get that does not use the system's DNS to resolve domains. To fix this you may need to add the following line to /etc/hosts (you can edit this file with sudo nano /etc/hosts or sudo gedit /etc/hosts):

 extras.ubuntu.com       91.189.92.152
