Ubuntu 24.04.5 Pulled: Understanding the Installer Bug Affecting Your Desktop ISO

Canonical has temporarily pulled the Ubuntu 24.04.5 desktop ISO following reports of a critical installer bug. Learn how this impacts your system setup and what you should do instead.

If you were planning to perform a fresh install of Linux, you might have noticed that Ubuntu 24.04.5 has been temporarily pulled from the official download servers. Canonical took this step after discovering a recurring bug that causes the installer to crash during the setup process, specifically when users select the extended installation options.

The Ubuntu 24.04.5 Installer Issue Explained

The fifth point release of Ubuntu 24.04, which arrived on September 10, was intended to provide updated media powered by the Linux 7.0 kernel. Unfortunately, users attempting to utilize the extended installation path encountered a fatal error. The root cause appears to be lingering configuration references related to TPM-backed full-disk encryption.

Even though the necessary components for this encryption feature were removed from the ISO, the subiquity installer was still looking for them. This conflict triggers a crash, rendering the installation process incomplete. It is a classic case of digital debris causing real-world headaches for system administrators and home users alike.

What You Need to Know About the Affected ISO

Before you panic about your current installation, it is important to clarify the scope of this issue:

  • Affected Media: Only the standard amd64 Ubuntu desktop image for version 24.04.5 is impacted.
  • Trigger Condition: The bug specifically manifests when users select the ‘extended’ install options during the setup routine.
  • System Impact: If you are already running Ubuntu, this does not affect your existing OS stability; it is strictly an issue with the new installation media.

Pro Tip: If you are looking to perform a clean install, stick with previous verified point releases or wait for Canonical to push out the corrected ISO files.

Moving Forward: What Should Users Do?

Canonical is actively working to resolve this discrepancy. If you have already downloaded the 24.04.5 ISO, it is best to delete it to avoid potential installation failures. Keep an eye on official Ubuntu channels for the re-release of the media. For those who absolutely must install the OS today, utilizing an older point release and upgrading via the terminal post-install remains the most reliable workaround to ensure a smooth desktop experience.
