I’m using Ubuntu 17.04 on my laptop. I’m not sure how the issue started since it is by no means a fresh install. I’m unable to resolve any DNS hostnames via browser or telnet. I’ve confirmed this on the laptop in question over multiple WiFi networks. I also confirmed that other devices on the same network are not experiencing this issue. I can ping any external IP address (e.g. 188.8.131.52) just fine. I can also visit websites by typing the IP address into the browser.
Things I have tried:
I tried running
sudo dpkg-reconfigure resolvconfto no effect.
I’ve also tried going into the network settings for the WiFi network and changing the Method to “Automatic (DHCP) addresses only”, then manually adding DNS server addresses.
I also tried adding a
supersede domain-name-serversline in my
etc/dhcp/dhclient.conffile which did not resolve the issue either.
I even manually edited my
/etc/resolv.confto replace my nameserver with 184.108.40.206.
Adding dns-nameservers to
/etc/network/interfacesfile has not helped either.
After each of these experiments failed to enable DNS lookups I restored the original config. I’m not able to install external packages right now such as dnsmasq. Can anyone point me in the right direction? I really am not sure how I got in this mess, but it’s persistent after rebooting as well. I’m not behind a VPN.
