looks like a connection error.... did you try running again? — Joshua Besneatte, May 11 '18 at 14:04
14.04 should still be supported for another year, right? so this https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release doesn't apply? — Joshua Besneatte, May 11 '18 at 14:09
@JoshuaBesneatte yea. I tried multiple times but it gives the same error again and again — Rishab Prasad, May 11 '18 at 14:11
can you ping the servers? could be DNS issue... see this: https://askubuntu.com/questions/29071/apt-get-update-cannot-find-ubuntu-servers — Joshua Besneatte, May 11 '18 at 14:16
@JoshuaBesneatte cannot ping
support@node:~$ ping us.archive.ubuntu.com ping: unknown host us.archive.ubuntu.com — Rishab Prasad, May 11 '18 at 14:18
probably DNS issue... add the google dns servers to /etc/network/interfaces -> dns-nameservers 8.8.8.8 8.8.4.4 per the second answer here: https://askubuntu.com/questions/130452/how-do-i-add-a-dns-server-via-resolv-conf — Joshua Besneatte, May 11 '18 at 14:26

If you can ping IP addresses but not domain names, you have a problem with your DNS. Adding the google DNS (8.8.8.8 and 8.8.4.4) to /etc/network/interfaces and restarting should solve your problem:

auto eth0
iface eth0 inet static
    . . .
    dns-nameservers 8.8.8.8 8.8.4.4

can you post your /etc/network/interfaces content into your question? – Joshua Besneatte May 11 '18 at 16:48
