Xperia M5 not updating to marshmallow

[dx1]

I recently tried to update my xperia M5 device to marshmallow through pc companion, the update was downloaded but when I connected my device through the cable then a messge appeared on the screen of my device which read that ''Unfortunately, update service has stopped''. Hence, I just couldn't update my device.

You have to wait a while longer, also when that happens just tap ok and then the Xperia Companion will tell you what to do next .

Connect the Xperia M5 to pc companion after download the updated software it require you to turn off the device and disconnect the phone to USB. Just restart the device while holding the down volume do not disconnect the usb cable this is to be able to continue updating the device.

Tried this method as well but still the same problem persists. Now the thing I'm looking forward is for the ota update to arrive.

When will the marshmallow update be available for Xperia M5 dual via ota?
