The mini iso uses a text-based installer, making the image as compact as possible. The download time savings achieved by using a mini iso can be significant, as only current packages are downloaded, so there is no need to upgrade packages immediately after installation. Downloading packages at install time reduces the size of the iso image to approximately ~40MB depending on architecture (see below), as well as providing only the packages needed for installation. The minimal iso image will download packages from online archives at installation time instead of providing them on the install media itself. They existed as a by-product of building the old server installer (based on "debian-installer" later called "alternative installer"). These images, which Canonical and the Ubuntu project never officially supported, were always limited to BIOS booting on the amd64 and i386 platforms only. Ubuntu 18.04 LTS was the last Ubuntu release which "mini.iso" images were produced for. On the installation target, cloud-init handles the initial network configuration. It was previously referred to as "server live installer". This installer is based on the Subiquity installer software. Get help migrating to the current Ubuntu Server installer on Ubuntu Discourse!
