Ubuntu 24.04.5 Installer Pulled After Installation Failures

Users attempting to install the newest version of Ubuntu on standard 64-bit systems have encountered a significant obstacle. The installation process fails completely if users select the extended installation option. This issue has forced the developer to withdraw the release from public distribution.

The problem stems from a mismatch between the installation software and the underlying system files. Specifically, the installer tries to use security features that are no longer present in the package. This leads to a crash before the operating system can be fully set up on the hardware.

Missing files broke the setup

The root cause involves a specific security feature known as TPM-based full disk encryption. Recent updates removed the necessary files for this feature from the installation image. However, the installation tool still assumes these files exist. When the tool tries to access them, it fails to handle the absence gracefully, resulting in a system halt.

According to reports from XDA Developers, the installer does not simply ignore the missing components. Instead, it attempts a partial fallback that leaves the system in an unstable state. This behavior makes the extended install option unusable for most users, effectively rendering the new release broken for a common use case.

Downloads now serve older version

To prevent further confusion, the developer has adjusted its download servers. If a user requests the 24.04.5 installer for standard 64-bit architectures, the server now delivers the previous stable version, 24.04.4. This ensures that users receive a working product, although the version number on the page may still display the newer iteration.

This workaround applies only to the standard desktop and laptop builds. Other variants, such as the server edition or those for different processor architectures, are not affected by this specific bug. These versions continue to function as intended because they do not rely on the removed security files in the same way.

Fix expected in coming updates

The developer has acknowledged the issue and is working on a permanent solution. The fix requires updating the installation tool to correctly detect the absence of the security files. Once this logic is corrected, the installer will simply skip the optional security feature rather than crashing.

Until the corrected installer is released, users should stick to the previous version or avoid the extended installation path. This incident highlights how critical dependency management is in operating system releases, where a single missing file can disrupt the entire deployment process.
