Ubuntu setup(but without bloatware)

Download ubuntu(server) from: https://ubuntu.com/download/server.

In linux you can make bootable usb using dd command:

sudo dd if=file_name_ubuntu_server.iso of=/dev/sdX bs=4M status=progress

In windows you can use tool like rufus:
https://rufus.ie/

After installation (first boot)

sudo apt update
sudo apt dist-upgrade

sudo apt install gdm3
sudo apt install gnome-terminal --no-install-recommends \
  --no-install-suggests

reboot

After reboot GUI and gnome-terminal should be available.

Network configuration

In ubuntu server(and/or maybe in generic ubuntu too) you have configure network using netplan package. By default netplan config is located in /etc/netplan/*.yaml.

config example:

network:
  renderer: NetworkManager
  ethernets:
    eth0:
      dhcp4: yes
      optional: true
      match:
        macaddress: aa:aa:aa:aa:aa:aa
      set-name: eth0
    eth1:
      dhcp4: false
      optional: true
      match:
        macaddress: bb:bb:bb:bb:bb:bb
      set-name: eth1
    wlan0:
      dhcp4: true
      optional: true
      match:
        macaddress: cc:cc:cc:cc:cc:cc
      set-name: wlan0
  version: 2

Other things what you can do with netplan:

• Disable "waiting for the network" (option parameter)
• Set logical interface names (set-name)
• Repin network adapters to NetworkManager (some network adapters might not show up in NetworkManager)

Expand LVM (disk space)

For some uknown reason ubuntu was using only half of my disk space(you can check with sudo pvscan command).
