Ubuntu announced the Trusty Tahr 14.04 LTS Final Beta on March 27, 2014, ahead of the stable release on April 17. The beta was test media, not the final supported build—and Ubuntu 14.04 is now an obsolete release whose listed extended security maintenance ended in May 2024. For historical use, Ubuntu’s archive offers the later 14.04.6 images; for an everyday computer, choose a currently supported Ubuntu release instead.
What “Ubuntu 14.04 Final Beta” meant
Ubuntu’s March 27, 2014 announcement described a pre-release snapshot intended for testing. Adam Conrad, an Ubuntu team representative, said the images were “known to be reasonably free of showstopper CD build or installer bugs” and represented a recent snapshot of the features intended for the April 17 final release. That was an assessment of the beta at the time—not a present-day assurance about archived media, hardware compatibility, or security.
The announcement covered Ubuntu Desktop, Server, Cloud, and Core, along with images for Edubuntu, Kubuntu, Lubuntu, Ubuntu GNOME, UbuntuKylin, Ubuntu Studio, and Xubuntu. Mythbuntu was expected to participate in the final release, although it was not included in the final beta. The beta announcement linked to beta-2 download directories and Trusty upgrade notes; those are historical links, not a current upgrade route.
Beta, stable release, and the later archive image
| Option | What it is | What to know |
|---|---|---|
| 14.04 Final Beta | Pre-release testing media announced March 27, 2014. | Not the stable release. Ubuntu expected the final release on April 17. |
| Ubuntu 14.04 LTS stable | The release published April 17, 2014. | Its support periods varied by edition and flavor. |
| Ubuntu 14.04.6 LTS | A later archived point-release image listed by Ubuntu. | Use only for a specific legacy need; it is not a currently supported release. |
Ubuntu’s stable-release announcement said that Desktop, Server, Cloud, Core, Ubuntu Kylin, Edubuntu, and Kubuntu had five years of maintenance, while the remaining flavors had three years. These are the periods announced in 2014, not current support coverage.

Support status: 14.04 is no longer maintained
Ubuntu’s lifecycle page lists standard security maintenance for 14.04 as ending in April 2019 and extended security maintenance as ending in May 2024. Both dates have passed. An ISO remaining available in an archive does not mean it still receives security fixes or is appropriate for internet-connected daily use. Ubuntu’s release-cycle page gives the lifecycle dates, and its releases index distinguishes standard-supported versions from ESM archive entries.
Where to get 14.04.6 for a legacy installation
If you have a concrete reason to install Trusty—for example, reproducing a legacy environment—use Ubuntu’s 14.04.6 archive page, rather than treating the 2014 beta directories as the normal download. The page lists desktop and server installation images and provides AMD64 and i386 options. It also links to guidance for writing an image to installation media.
Choose the edition and architecture deliberately
- Desktop or server: Select the image that matches the machine’s intended role. The archive lists separate desktop and server images.
- AMD64 or i386: Ubuntu’s archive guidance suggests AMD64 for suitable 64-bit PCs. It identifies i386 for non-64-bit AMD processors or when full 32-bit code support is needed. Check the actual processor and software requirements rather than guessing from the computer’s age or brand.
- Installation media: A USB flash drive is optional physical media for writing an image. Ubuntu’s archive does not establish a required model or capacity.
Ubuntu’s 14.04 release notes list archived ISO locations by edition and flavor. Verify the exact image and architecture on the official page before using it.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Fresh install or upgrade from an existing Ubuntu system?
Downloading an ISO for a fresh installation is different from upgrading an existing installation in place. The 14.04 release notes describe the procedures from that release era: desktop users launched Update Manager, while server users used do-release-upgrade. The notes also say the server upgrade tool could reattach after a dropped connection. These historical directions do not establish a supported direct upgrade path from every old or intermediate Ubuntu version today.

Before changing an existing system, check the current Ubuntu upgrade guidance for the exact installed release and the intended destination release. Back up important data, confirm the supported upgrade sequence, and avoid assuming that a 14.04-era instruction remains a safe or supported path.

Should you download it now?
- For a normal PC or server: No. Install a currently supported Ubuntu release rather than 14.04 beta or archived 14.04.6 media.
- For legacy testing or recovery: The archived 14.04.6 image may be relevant, but first verify the architecture, edition, and compatibility needs.
- For a historical reference: The beta announcement and release notes document what was available and how upgrades were handled at the time.
