Device Update to Ubuntu 16.04



This article explains the benefits of the device update to Ubuntu 16.04 and the process to complete the update.

Because this update requires you to accept a third-party licensing agreement, Datto Technical Support cannot perform the initial install of Ubuntu 16.04 on your behalf. Please contact us if you encounter difficulties during the installation. 


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
If you have ownCloud on SIRIS installed on the device, the device update is not yet available.

Installation Requirements

  • 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.

Figure 1 - The device has active restores

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.

If you get a message stating that the upgrade cannot occur because of active recovery points, see this article.

You will get a message explaining that the process will take some time and require a reboot, as shown in Figure 3.

Figure 3 - OS Upgrade Notification box

You must check in the box for "Allow installation of third party software and drivers."

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.

If you run into any trouble with the upgrade, contact Datto Technical Support.

    Device was updated to 16.04, and now only one of my devices is able to connect. Getting backup errors on all other hosts. Thoughts?
