Unraid 6.12.3 Now Available

Unraid 6.12.3 is available and has a set of bug fixes for networking and Docker.

Home 6 12 stable 4

The 6.12.3 release includes a set of bug fixes for networking and Docker. All users are encouraged to upgrade.

Please also refer to the 6.12.0 Announcement post.

Upgrade Steps for this Release

  1. As always, before upgrading, create a backup of your USB flash device: "Main/Flash/Flash Device Settings" - click "Flash Backup."
  2. Update all of your plugins. This is critical for the NVIDIA and Realtek plugins in particular.
  3. If the system is currently running 6.12.0 - 6.12.2, we're going to suggest that you stop the array at this point. If it gets stuck on "Retry unmounting shares", open a web terminal and type:

    umount /var/lib/docker

    The array should now stop successfully (This issue is resolved with this release)

  4. Go to Tools -> Update OS. If the update doesn't show, click "Check for Updates"
  5. Wait for the update to download and install
  6. If you have any plugins that install 3rd party drivers (NVIDIA, Realtek, etc), wait for the notification that the new version of the driver has been downloaded.
  7. Reboot

Version 6.12.3 2023-07-14

Changes vs. 6.12.2


This release has fixes for networking, particularly as it relates to IPv6. A side effect is that this should resolve an issue where the webGUI will not load in certain instances.

Note: If you have code in your 'go' script to disable IPv6, remove that and disable it via the 'Settings/Network Settings' page instead.

Manually disabling IPv6 will cause conflicts.


This release resolves an issue where Docker does not properly stop when the array Stops, which can result in an unclean shutdown.

If Docker containers have issues starting after a while, and you are running Plex:

  • Go to your Plex Docker container settings, switch to advanced view, and add this to the Extra Params: --no-healthcheck
