Whenever I restart my computer NetworkManager sets
/etc/resolv.conf to this, my DNS stops working and I get this error in Chrome.
# Generated by NetworkManager search tampabay.rr.com nameserver 127.0.0.53
I temporarily resolve the issue by setting
/etc/resolv.conf to this.
I'm guessing NetworkManager expects a DNS server on my local machine at 127.0.0.53, and I don't have DNS running there. How can I permanetly set
18.104.22.168 as my nameserver? If it's really neccessary how do I setup DNS at
man resolv.conf but it didn't help me much.
I read this answer and created the file
nameserver 22.214.171.124 but it doesn't seem to have any effect: DNS set to systemd's 127.0.0.53 - how to change permanently?
Edit: Ubuntu 20.04 LTS
The DNS cache program
unbound was running on port :53 and preventing
dnsmasq from starting. I uninstalled
dnsmasq starts now. However it's saying it's only running on 0.0.0.0 for some reason. I figure it has to be running on 127.0.0.1:53. I reinstalled dnsmasq but it's acting the same.
/etc/dnsmasq.conf is all commeted out.
/etc/resolv.conf is now set to
# Generated by resolvconf nameserver 127.0.0.1
Not sure how to get
dnsmasq running properly.
