Sometimes, when installing the Ubuntu 24.04 TLS Server ISO image, the process freezes at one of the stages. There are already many discussions about this problem online. The solution is to install the distribution with the network disabled.

To configure the network on the Linux Ubuntu 24.04 distribution after installation, you need to:

1. Log in as the root user

If the installation has just finished, log in as the user you created and set a password for the root user.

sudo passwd root

Impersonate the root user using the command and the password you set.

su -

2. Network configuration, static IP address

Create a configuration file

touch /etc/netplan/00-installer-config.yaml
vi /etc/netplan/00-installer-config.yaml

With the following content:

network:
    version: 2
    renderer: networkd
    ethernets:
      enp0s3:
        addresses: 
          - 89.111.187.xxx/24
        gateway4: 89.111.187.x
        nameservers:
          addresses: [8.8.8.8, 1.1.1.1]

Apply the configuration

netplan apply

Note 1

If errors occur, check the file for tabs

cat -A /etc/netplan/00-installer-config.yaml

If you see ^I - these are tabs. Replace them with spaces!

You can check with the ping command by external IP address and domain.

Note 2

If ping only works by IP address, check for the presence of the following lines in the file:

/etc/resolv.conf

nameserver 8.8.8.8
nameserver 1.1.1.1
