I know there is an easy fix to the problem by adding
nameserver 8.8.8.8
to /etc/resolve.conf but this is merely a hack and not a proper trouble shoot of the problem that caused the problem. If I am not wrong having the 'default'(or what do you call it ?) nameserver 127.0.0.53 should be enough on a fairly new Linux system (Ubuntu 16.04). I have gone through other related questions here and tried all those but to no avail. Some of the things I tried:
- Connecting through different NIC ( wlan0, Eth0 )
- configuring static IP (with google's DNS ) as well as dynamic IP ( with the default gateway [192.168.43.1] as the DNS.
But all without any success. I had some boot issues with the hard drive (my hard drive became unbootable for sometime because apparently there was some issue with bootloader which I fixed later with boot-repair).
In short, I can't ping google.com if there is nameserver 127.0.0.53 . But I can ping if I add nameserver 8.8.8.8
If anybody can help me to right direction that would be great. Thanks.
Update:
If it helps, I actually have dual boot system with Lubuntu 18.10 as well and it doesn't have the problem. the /etc/resolve.conf file has nameserver 127.0.0.53 .
