Ubuntu 25.04 ISO Download Guide

Ubuntu 25.04 is an interim release that arrives six months after the previous LTS version. Unlike long-term support releases, interim versions receive nine months of security updates and maintenance. Plucky Puffin includes the latest kernel, updated package repositories, and improvements to system performance. This release targets users who want newer software and hardware support without waiting for the next LTS cycle. It's suitable for workstations, development environments, and servers that don't require extended support periods.

Ubuntu 25.04 was released in April 2025, following Canonical's predictable six-month release schedule. The ISO files became available immediately on the official Ubuntu mirrors and download servers. You can download the ISO from the main Ubuntu website or through regional mirror sites, which may offer faster speeds depending on your location. The release includes both desktop and server variants, each optimized for its intended use case. Interim releases typically receive updates throughout their support window, so checking for updates after installation is recommended.

Visit the official Ubuntu download page and select the 25.04 version. You'll find options for desktop and server editions. Desktop comes with the GNOME graphical interface, while server provides a minimal installation for headless systems. Download the ISO file directly to your computer. The file size is typically around 4-5 GB for desktop and smaller for server editions. After downloading, verify the file's SHA256 checksum against the published hash to ensure the download completed without corruption. This verification step protects against accidental data loss during installation.

Ubuntu 25.04 is an interim release, not an LTS version. LTS releases receive five years of support, while interim releases like 25.04 receive nine months. The next LTS release will arrive in April 2026. Interim releases prioritize delivering new features and software updates quickly, making them ideal for users who want the latest tools. LTS versions prioritize stability and long-term compatibility, better suited for production servers and conservative deployments. Choose 25.04 if you value recent software; choose an LTS release if you need extended support and predictability.

After downloading the ISO, you need to write it to a USB drive or DVD. On Linux, use the dd command or Etcher tool. On Windows, tools like Rufus or Etcher work reliably. Insert a blank USB drive with at least 8 GB capacity, select the Ubuntu 25.04 ISO file, and start the write process. The tool will overwrite the USB drive's contents, so back up any existing data first. Once complete, insert the bootable media into your target computer, restart, and boot from the USB drive. The installation wizard will guide you through partitioning, user account setup, and software selection.

If you're running Ubuntu 24.10 or earlier, you can upgrade to 25.04 without reinstalling. Open the Software Updater application, which will detect the new version and prompt you to upgrade. Alternatively, use the command line with update-manager or apt commands. Back up your important files before upgrading, as the process modifies system files. The upgrade typically takes 30-60 minutes depending on your internet speed and system performance. After upgrading, restart your computer and verify that all applications and settings work correctly.

Ubuntu 25.04 desktop requires a 2 GHz dual-core processor, 4 GB RAM, and 25 GB disk space for comfortable operation. Older hardware with 2 GB RAM and 10 GB storage can run it, but performance will be limited. Server edition has lower requirements and runs on minimal hardware. An internet connection is helpful for downloading updates during installation. GPU acceleration is optional but improves performance on systems with compatible graphics cards. Check your hardware specifications before downloading to ensure compatibility.
