  • Can you access any site on the internet at all from that system? – nobody special Aug 23 '18 at 19:28
  • no,I am not able access any sites through terminal and I am not able to install any thing – Avinash Avi Aug 24 '18 at 22:12
  • Going to need more information for anyone to be able to help you. Edit your question with the following information. Post the output of this command ifconfig and this command cat /etc/network/interfaces and this command cat /etc/resolv.conf and this command sudo lshw -C network and this command iwconfig and this command ip link and this command ip rule and this command ip route and this command lspci -nnk and this command dmesg | grep net – nobody special Aug 25 '18 at 02:34
  • Those commands should give a better insight to the problem. Is it a dual boot system, and if so does the network work in the other system? If it is a cable network, check that the cable is plugged in to the computer and router properly, check you have leds on, and tell us what colours they are. Are you using a wifi or cable network connection. – nobody special Aug 25 '18 at 02:34
  • Yes, Mine is dual boot system with Ubuntu 18.04 and Windows 8.1. I am connected to cable network with proxy authentication and it is plugged and working in windows.I am able to access internet through chrome in Ubuntu. But when I am trying to run update or upgrade commands I am getting the above errors – Avinash Avi Aug 26 '18 at 08:12

  • How I can resolve this error – Avinash Avi Aug 26 '18 at 12:08
  • Okay, add in the output from systemd-resolve --status (I should have asked for that before), and also from ping -c 5 8.8.8.8 and mtr 8.8.8.8 if mtr is not on your system, add it by this command sudo apt-get install mtr-tiny – nobody special Aug 26 '18 at 12:32
