问题:
Till few days back the Dockerfile was working fine and when i tried to build it again today it is giving following error in the terminal. I tried with multiple docker base images but still giving the same error. Can any one help me with this? I dont think i missed out anything. If i had missed it should have given me the error earlier itself but why now?

Looks like you have a connection error in your RUN instruction.
Try doing the same commands in an Ubuntu Container.
docker run -it ubuntu bash
And then inside the container do your RUN command.
On my machine, your script does work.

I just changed my VM players network setting. Changed Network Connection from bridged mode to NAT. Now its working

If your host is an Ubuntu VM, it could be an invalid /etc/resolve.conf. Look at the /etc/resolv.conf on the host Ubuntu VM. If it contains nameserver 127.0.1.1, that is wrong.
Run these commands on the host Ubuntu VM to fix it:
sudo vi /etc/NetworkManager/NetworkManager.conf # Comment out the line `dns=dnsmasq` with a `#` # restart the network manager service sudo systemctl restart network-manager cat /etc/resolv.conf
Now /etc/resolv.conf should have a valid value for nameserver, which will be copied by the docker containers.

A simple method could be write the nslookup archive.ubuntu.com IP to the /etc/hosts, then restart docker.
Of course it needs your docker 's /etc/docker/daemon.json use host machine 's IP.

Overview
There are two parts to your question:
1. fixing temporary resolve messages
2. fixing the package management issues
Temporary resolve
It is likely that this issue is either:
1. temporary due to your Internet Service Provider not correctly forwarding internet naming (DNS) to either its or external DNS servers, or
2. due to a change in your network has similarly blocked this naming - for example, new router/modem, reconfiguring a switch with a new configuration.
Let's look at the possible DNS resolving issues.
First, temporarily add a known DNS server to your system.
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null
Then run sudo apt update.
If this fixes your temporary resolving messages then either wait for 24 hours to see if your ISP fixes the issue for you (or just contact your ISP) - or you can permanently add a DNS server to your system:
echo "nameserver 8.8.8.8" | sudo tee /etc/resolvconf/resolv.conf.d/base > /dev/null
8.8.8.8 is Google's own DNS server.
source
Another example DNS server you could use is OpenDNS- for example:
echo "nameserver 208.67.222.222" | sudo tee /etc/resolvconf/resolv.conf.d/base > /dev/null
package-management issues
In addition to the temporary resolve issues - you have a few package management issues that need to be corrected.
Open a terminal and type:-
sudo nano /etc/apt/sources.list
and look if you are downloading from right source package.
OR
if you are behind proxy use -E.for example:-
sudo -E apt-get update
