On the DVD

This latest long-term support distribution is built on Linux kernel 5.4 and comes with "enterprise-class stability, resiliency, and even better security" [1]. New to Ubuntu Server is the easy-to-use, cryptographically sound WireGuard VPN [2]. The bootloader can now be written to multiple disks, removing a single point of failure. Also new to version 20.04:

• Updated Live installer
• New Ubuntu Server Guide
• SSH support for hardware-based two-factor authentication
• Runs on all major architectures
• Updated applications

Canonical support for Ubuntu Server 20.04 LTS (Focal Fossa) extends to 2025, with end of standard maintenance (ESM) coverage to 2030.
