I am trying to run apt update on Ubuntu 14.04 installed from trusty-server-cloudimg-amd64.ova.

I can see the apt-get traffic is being allowed in the firewall.

I ran sudo apt update and below is what I get:

Err http://minmeld-updates.pan.io trusty-minemeld InRelease

Err http://minmeld-updates.pan.io trusty-minemeld Release.gpg
  Could not resolve 'minmeld-updates.pan.io'
Ign http://security.ubuntu.com trusty-security InRelease
Ign http://archive.ubuntu.com trusty InRelease
Ign http://minemeld-updates.panw.io trusty-minemeld InRelease

    Could you please add a little more detail? What exactly did you do, what did you expect to happen and what happened instead? Did you encounter any warning or error messages? Please reproduce them in their entirety in your question. You can select, copy and paste terminal content and most dialogue messages in Ubuntu. Please [edit] your post to add information instead of posting a comment. (see How do I ask a good question?) – David Foerster Jan 23 '18 at 18:48

The problem seems to be in happening after the ubuntu 12.04, is a problem between the dnsmasq and resolvconf.

Be the correct way to fix it is to restart the network-manager service, to it get the right dns:

sudo service network-manager restart

Or

install resolvconf

sudo apt install resolvconf

Start by pinging the server:

ping -c 4 archive.ubuntu.com

if you can reach it, which looks like this:

$ ping -c 4 archive.ubuntu.com
PING archive.ubuntu.com (91.189.88.161) 56(84) bytes of data.

you can try disabling IPv6 addressing in GUI:

  • In the top right find the networking indicator icon

  • Select edit connections

  • Edit you current connection (double-click)

  • Under IPv6 settings/method, choose Ignore

  • Save and exit

  • Try it!

  • Update us

Or CLI:

$ sudo sh -c 'echo 1 > /proc/sys/net/ipv6/conf/eth0/disable_ipv6'

Of course, you should replace 'eth0' with any other interface if it's not the one you're using, or 'all' to do it on all interfaces. This will only work until you reboot though.

  • This is a server with no gui. Not sure how to disable ipv6 on it. – Flaster Jan 23 '18 at 18:10

  • can you confirm you only have an ipv4 address in ifconfig? – Schtromar Jan 23 '18 at 18:59

  • I'm afraid this is as much help as i can give you. You did 'apt-get update' right? – Schtromar Jan 23 '18 at 19:34
  • Thank you so much for your help. It is still failing but I appreciate your time! – Flaster Jan 23 '18 at 19:53
