Canonical has laid down their plans for the Ubuntu Server installer for the upcoming Ubuntu 20.04 LTS (Focal Fossa) operating system series. During the development cycle of the Ubuntu 20.04 LTS operating system, which should debut in late April 2020, Canonical wants to make the Ubuntu Server installer faster and more comfortable for its server users by dropping support for the Debian-installer based classic server installer and replacing it with their more modern, in-house built subiquity server installer.
