Unraid 6.12.2 update is now available

The Unraid squad has rolled out an update for the popular NAS operating system. This release brings the version up to 6.12.2 and includes bug fixes as well as a few changes. Most notably, the Linux kernel has been bumped up to version 6.1.36.

What is in Unraid 6.12.2?


  • We reverted docker from v23.0.6, introduced during Unraid OS 6.12 development, to v20.10.24, which is the latest patch release of docker used in Unraid OS 6.11. This is to address increased memory usage and other issues discovered with docker.
  • A small necessary change to invoke our ‘update_services’ script whenever a WireGuard tunnel starts or stops is automatically applied to all ‘config/wireguard/*.conf’ files when you update via the Update OS page. For manual updates or if you downgrade, it is necessary to make a “dummy change” in a setting on the Settings/VPN Manager page and then click Apply.
