Remove any USB drive and other peripherals connected to the device (this is just to play it safe)
Open the Volumio app → home page → select the device → press on the hamburger menu icon ≡ on the top left of the screen → select System → scroll until you see System Updates → press on Check Updates
A pop-up will appear at the top of the screen → press on Update Now
Do not turn off the device or disconnect the power even if the update process seems stuck. This may take several minutes depending on your internet connection and the update itself, but don’t worry: sip some tea or coffee while it does its thing
Enjoy!
