This article explains the benefits of the device update to Ubuntu 16.04 and the process to complete the update.
The device update to 16.04 brings all the benefits of SIRIS 3 to your Datto appliances:
- Advanced features and hardware support of Ubuntu 16.04
- Datto Next Generation Bare Metal Restore
- Apache Webserver replaces Cherokee Webserver to deliver enhanced Remote Web performance
- SIRIS 3's underlying architecture leverages PHP7+FPM to improve responsiveness, stability, and reliability
- KVM, rather than VirtualBox, as the virtualization hypervisor
- The target system must be a SIRIS 2, SIRIS 1, SIRIS Lite, Alto 2, Alto XL, Virtual SIRIS, Virtual Alto, or a GENISIS-converted appliance.
- 5 GB free space on the OS drive (verifiable through the Advanced Device Status tab of the GUI)
- No restores mounted
- Up to 1 hour to run the update
The device upgrader will attempt to verify that the unit is not being used for any purposes related to disaster recovery or backup verification before running. If the upgrader detects the device is being used to export disk images, perform a file-level restore, run screenshot verification, or virtualize a protected machine, you will see an error message as shown in Figure 1.

If you see this error, follow the instructions in the KB article Can't Update Device Because Of Active Restores.
To upgrade your device, open the web interface.
Start the update process by clicking on the Configure tab, and then click Device Update.
The page should look similar to Figure 2.
Figure 2 - Select Updates
Check the box in the Select Updates column, and then click Start Update.
You will get a message explaining that the process will take some time and require a reboot, as shown in Figure 3.

Click the Upgrade Now button to start the process. You will then see a progress bar, as shown in Figure 4.
Figure 4 - Upgrade Process
This part of the upgrade process may take anywhere from 45 minutes to more than an hour to complete. Since the Datto device must download packages as part of the upgrade process, sites with low available bandwidth may experience significantly longer upgrade times. However, it will not need further intervention from you. When the process finishes, Remote Web will display the box as shown in Figure 5.
Figure 5 - Rebooting Device
After the reboot process is complete, refresh the web browser. You will see the window as shown in Figure 6. This indicates that the device successfully upgraded to Ubuntu 16.04.
