Cannot find netboot mini iso for Ubuntu Groovy 20.10

For the i386 architecture, you can download it here http://archive.ubuntu.com/ubuntu/dists/groovy/main/installer-i386/current/images/netboot/mini.iso

When I click on this link this installation option is displayed http://archive.ubuntu.com/ubuntu/dists/groovy/main/installer-amd64/current/legacy-images/

netinstall

Netbooting the server installer on amd64

Netbooting the live server installer This is now the only option for netinstall Ubuntu Groovy 20.10 amd64?

The Canonical decided to stop providing this image. See these topics on Ubuntu Community and LaunchPad:

As the workaround use 20.04 LTS netboot mini iso from

http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/current/legacy-images/netboot/

and then upgrade it to groovy by do-release-upgrade after installation.

There is no mini.iso for Ubuntu 20.10. Not the same, but you can install minimal system using debootstrap. To show this method, I will use Ubuntu 20.10 live iso booted from usb. In terminal:

sudo su -
# Install debootstrap
apt update
apt install debootstrap

Partitioning


fdisk -l
mkfs.ext4 /dev/sdaX


mount /dev/sdaX /mnt


Install base packages


debootstrap groovy /mnt


mount /dev /mnt/dev --bind
mount /proc /mnt/proc --bind
mount /sys /mnt/sys --bind


Go inside new system


chroot /mnt


Install the Linux kernel and text editor


apt update
apt install linux-image-generic nano


Check UUID and paste it into /etc/fstab


blkid | grep sdX > /etc/fstab


Edit fstab so it looks like this:


UUID=<your uuid> / ext4 errors=remount-ro 0 1


nano /etc/fstab


Install boot-loader (Legacy BIOS)


On UEFI, change the target to i386-efi


grub-install --target i386-pc /dev/sdX


Optionally, edit grub settings in /etc/default/grub


update-grub


Add user


adduser <name>
usermod -aG sudo <name>
passwd <name>


Set time and language


dpkg-reconfigure locales
dpkg-reconfigure tzdata
dpkg-reconfigure keyboard-configuration


Set hostname


nano /etc/hostname

Fix NetworkManager if you install this way: Ethernet device not managed
