The TrueNAS Update screen provides users with different methods to update the system automatically or manually. The screen can show up to four information areas:

• Current train
• Upgrade operation and version (only when an update is detected)
• Production/non-production release information (only when an update is detected)
• Update options

The screen shows the Current Train and a link to more information on the current train.

Check for Updates Daily and Download if Available sets TrueNAS to check the update server daily for updates on the specified train. When selected, the system automatically downloads an update if one is available. The refresh refresh button refreshes the information displayed on the screen.

TrueNAS has several software branches (linear update paths) known as trains. If TrueNAS is in a prerelease train it can have various preview/early build releases of the software.

The Update Screen only displays the current train. When upgrading TrueNAS to a new major version, follow the upgrade path of major versions until the system is on the desired major version release. For more information on other available trains and the upgrade path from one version to the next, see Software Releases.

After you download the .iso file, you can start installing TrueNAS!

This article describes verifying the .iso file, then installing TrueNAS using that file, and selecting the type of installation as either on physical hardware or a virtual machine (VM).
