Effective immediately, the upgrade path from AnduinOS 1.3.9 to AnduinOS 1.4.2 is open to all users. Due to the imminent End of Life (EOL) of the upstream base, we strongly advise all users on the 1.3 branch to upgrade as soon as possible.

AnduinOS 1.3 is derived from Ubuntu 25.04 (Plucky). Upstream maintenance for Ubuntu 25.04 will officially cease on January 30, 2026. After this date, security updates and repository access for the 1.3 branch cannot be guaranteed.

Upgrade Procedure

The upgrade process has been automated via the terminal. To initiate the upgrade, execute the following command:

do_anduinos_upgrade

Estimated Duration: 1 to 2 hours. System Impact: The system may reboot during the process.

Technical Workflow

The do_anduinos_upgrade utility performs the following sequential actions:

  1. Version Check: Validates the current version. If the system is running a version prior to 1.3.9 (e.g., 1.3.7), it will first update to 1.3.9.
  2. Repository Migration: Modifies APT software sources from plucky to questing.
  3. System Update: Executes a full system-wide package upgrade.
  4. Version Increment: Updates the system version identifier to 1.4.2.
  5. Image Acquisition: Downloads the AnduinOS 1.4.2 ISO (matching the current system language) via BitTorrent/aria2c.
  6. System Repair & file replacement: Mounts the ISO and performs an automated repair, replacing critical system files with those from the 1.4.2 release.
  7. Reboot: Restarts the system to apply changes.

Critical Warnings and Prerequisites

Before proceeding, you must adhere to the following:

  • Data Backup: Perform a full backup of all critical data and user configurations.
  • Service Interruption: Stop all critical business applications and services.
  • Custom Kernel/Initramfs: This upgrade may overwrite manual changes to initramfs-tools or custom-compiled kernels. These will likely be rolled back to the distribution default.
  • Dracut: The upgrade process may disrupt dracut configurations.

Troubleshooting

This upgrade carries inherent risks. Please follow these recovery protocols if failures occur:

  1. Failure before version change: If the process fails while the system still reports version 1.3.9 (or lower), retry the command: do_anduinos_upgrade
  2. Failure after version change: If the system reports version 1.4.2 but is unstable or the process was interrupted, execute the auto-repair tool: do-anduinos-autorepair

Please leave feedback in the community in case any error occured.

Note on AnduinOS 1.1

This announcement applies strictly to the 1.3 branch. Users running AnduinOS 1.1 are unaffected by the upstream EOL and do not need to take action at this time.
