@RandomUser said in How to update Xenial to Focal?:
but of course the installation is interupted.
Hi,
In my experience it is not the case.
I force the fastboot mode by pressing the vol+power buttons and just continue the install.
I'm not sure whether I unplug the device or not, but I didn't have issue continuing or nothing that a retry couldn't fix.
But I have also to clarify that I don't own the same device and I know devices with A/B boot might have some additional complexity (not sure if that's the case of the OP6).
