DNS broke after resizing server and upgrading packages. How can I fix it?
I just resized my server and then did
sudo apt-get upgrade to update my packages, and now my server’s DNS is totally borked:
ping google.com ping: unknown host google.com
My resolv.conf is totally empty:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
I can edit my resolv.conf to fix the problem, but then my edits get blown away upon reboot and goes back to being empty.
What can I do to fix this? What more information can I provide?
