MAAS can't apt update

I'm setting up MAAS for our workstations and it's going great! I've deployed a test VM with it. The only thing that doesn't work is apt.

I can't perform an apt update. It looks for 172-16-0-0--16.maas-internal and I have no idea where it's getting it from.

This is the full output:

~# apt update

This is my /etc/apt/sources.list file:

# Aptly 
deb [trusted=yes arch=amd64] http://aptly/ bionic main universe 
deb [trusted=yes arch=amd64] http://aptly/ bionic-updates main universe
deb [trusted=yes arch=amd64] http://aptly/ bionic-security main universe

I also tried it with the default sources.list but it had the same error.

The /etc/resolv.conf file just points to my DNS server.

No matter what I put in my sources.list file it keeps complaining about 172-16-0-0--16.maas-internal. Why is it looking for 172-16-0-0--16.maas-internal? What is it? Can i go around it? Do I have to setup a new DNS record? How can I have apt working?

Huge thanks ahead!

Solution 1:

It looks like you have edited your network configs. If you have edited please try these steps:

1. You need to set MAAS IP address as the DNS of all your node you are trying to apt update.

Example

    enp3:
      match:
        macaddress: 62:34:0f:91:1b:e2
      addresses:
       - 172.168.0.12/24
      gateway4: 172.168.0.10
      mtu: 1500
      nameservers:
        addresses:
          - 172.168.0.16 #<<<< IP OF THE MAAS INTERFACE #
      set-name: enp3

2. Go to the MAAS Subnet and set the correct DNS Names. See attached screenshot.

3. Lastly, for the changes to take place, restart your maas network sudo systemctl restart systemd-networkd and your node or reboot.
