@abcabc123 Hmm - ok. Let’s try this instead

To set a permanent DNS on the latest version of Ubuntu (e.g., Ubuntu 22.04 or later), you typically configure DNS settings via Netplan, the network configuration tool. Here’s how you can do it:

---

1. Locate the Netplan Configuration File

Netplan configuration files are located in the /etc/netplan/ directory. Typically, the file is named something like 01-netcfg.yaml or 50-cloud-init.yaml. Use the following command to list the files:

ls /etc/netplan/

---

2. Edit the Configuration File

Open the appropriate Netplan file for editing. For example:

sudo nano /etc/netplan/01-netcfg.yaml

---

3. Modify the DNS Configuration

Add or modify the nameservers section under the relevant interface. Your file might look like this:

network:
  version: 2
  ethernets:
    enp0s3:  # Replace with your network interface name
      addresses:
        - 192.168.1.100/24  # Your static IP address (if applicable)
      gateway4: 192.168.1.1 # Your gateway address
      nameservers:
        addresses:
          - 8.8.8.8    # Primary DNS
          - 8.8.4.4    # Secondary DNS

• Replace enp0s3 with your actual network interface name, which you can find using:

  ip a
  

• Adjust the DNS servers (8.8.8.8, 8.8.4.4) to your preference.

---

4. Apply the Configuration

Save the file and apply the changes:

sudo netplan apply

---

5. Verify the DNS Configuration

Confirm that the DNS settings are applied:

systemd-resolve --status

Look for the DNS Servers under your active interface.

---

Additional Notes:

• If you use NetworkManager (common on desktop installations), you can configure DNS through the GUI or by editing /etc/NetworkManager/NetworkManager.conf.

• If your system uses systemd-resolved, ensure it’s enabled and running:

  sudo systemctl enable systemd-resolved
  sudo systemctl start systemd-resolved
  

This setup ensures the DNS settings persist across reboots. Let me know if you run into any issues!

Is that right?

[phenomlab]

@abcabc123 Looks correct, yes.

[abcabc123]

It’s too complicated, I’m new to linux

[abcabc123]

Ubuntu 22.04 operating system Can you install nodebb forum

[abcabc123]

What operating system, install nodebb forum is the best

[phenomlab]

@abcabc123 What happened to the build I completed yesterday? Have you erased it? If you have, I will not be rebuilding it again for you as this is not what this site is for. I am more than happy to provide assistance, but that does not extend to setting up and maintaining your instance for you.

Ubuntu is not complicated at all, but like all new technologies you are not conversant with, there is a learning curve, and you need to be prepared to invest the time in order to become comfortable with the system.

The approved build documentation can be found here

https://docs.nodebb.org/installing/os/ubuntu/

[abcabc123]

50 hours, the problem has not been solved. I’m going to give up

[abcabc123]

I think it’s most stable to install .nodebb with Ubuntu 22.04

[phenomlab]

@abcabc123 Ok, but make sure you go for the LTS version which is supported up until 2027. At some point, you will need to familiarise yourself with Ubuntu and Linux in general as you will not be able to support your NodeBB installation without that knowledge.

you surprise me

[abcabc123]

I use Ubuntu 22.04, can it help me to install, I really won’t install.

[phenomlab]

@abcabc123 Ubuntu 22.04 is fully supported so the installation will work fine if you follow the guide from NodeBB themselves IO posted earlier.

[abcabc123]

I tested it just now and it didn’t install successfully. Can you help me with the installation

[phenomlab]

@abcabc123 What part did not work? Did you use the guide?

[abcabc123]

The order is wrong, and there are some explanations that I don’t understand.
