Fixing DNS Resolution problems with Linux Mint 19

Fixing DNS Resolution problems with Linux Mint 19

Linux Mint 19 has an issue (at least on the machines I've installed it on) where resolv.conf has its nameserver entry pointing to 127.0.0.53. That works fine except for resolving local subnet names (in my case 196.168.1.x). The following fixes the symptoms, though I still don't know why 127.0.0.53 is being used instead of the assignment from DHCP.

Run in root console, or sudo:

# apt install resolvconf
# nano /etc/resolvconf/resolv.conf.d/tail
    nameserver 192.168.1.1
# resolvconf -u

This will tag the local nameserver entry onto the end of resolv.conf and persists through resets.
