On August 31, 2026, UGREEN released the new UGOS PRO version 1.19.1.0126. Below I will guide you step by step through the process of installing the new UGOS PRO 1.19.1.0126. This update upgraded the system Kernel to version 6.18. This newer Linux kernel delivers better hardware compatibility, improved power management, enhanced security foundations, and overall system stability. Linux Kernel 6.18 was released on November 30, 2025, and designated as a Long-Term Support (LTS) release supported until December 2027. Docker and related services also receive accompanying updates as part of the broader ecosystem refresh that accompanies major UGOS PRO releases. While firmware updates on UGOS PRO have historically been non-destructive, it is always prudent to ensure important files are protected (local copies, another NAS, or cloud storage following the 3-2-1 rule).

• STEP 1

Log in to your UGREEN NAS via the web interface. Open the Control Panel. On the left sidebar, under Service, click Update & Restore. The system will automatically check for available updates. When version 1.19.1.0126 is detected, click Update Now.

• STEP 2

The NAS will download the package, apply the update, and restart automatically. Typically, the update will last 1 or 5 minutes depending on your UGREEN NAS model and network speed. After reboot, log in again and verify the new version under Control Panel / Update & Restore.
