  • 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
