I cannot use apt update as every reboot my sudo vim /etc/resolv.conf file resets to the below

# Generated by resolvconf
search home

I have tried to change the nameserver to a proper DNS but it resets every reboot? How can I fix this?

  • The file is automatically generated. If this is missing it indicates some problem in your networking setup. You should specify what you have done.

As written in the first line of /etc/resolv.conf it is generated by resolvconf. If you want to set a static domain name server you have to uncomment in /etc/dhcpcd.conf the line:

#static domain_name_servers= fd51:42f8:caae:d92e::1

and set it to your name server and reboot. Maybe you have also to stop asking for a domain name server from your dhcp server. You can try to modify the line:

option domain_name_servers, domain_name, domain_search, host_name


option domain_name, domain_search, host_name
  • No. This file does not exist, and creating it doesn't change anything.

    @DanielF Of course does it exist. This is an accepted answer. As seen from the tags of the question we are talking about raspbian-stretch. So please use a default unmodified image from it and you will find /etc/dhcpcd.conf and /etc/resolv.conf because dhcpcd is the default networking management for Raspbian. If you have a problem with your setup then please open a new question.

  1. Open the following file:

    $ sudo vim /etc/resolvconf/resolv.conf.d/base

  2. Put your nameserver list in the file like those:

    nameserver nameserver

  3. Update resolvconf with the following command:

    $ sudo resolvconf -u

    The file doesn't exist and I cannot create it either with sudo or directly as root

  • I also know the trick with editing /etc/resolvconf/resolv.conf.d/base on my Ubuntu Server machines, but Raspbians resolvconf seems to work different. Even creating the missing resolv.conf.d directory and base directory and setting the same file permissions than on my Ubuntu permissions did not do the trick. Apr 23 '19 at 9:25
