After sudo apt upgrade - the wifi device is gone


Hi all,

I have used the following image and installed the OS in the emmc.

Initially, I have the desktop and I can setup the wifi connection as normal. Once I run the commands
sudo apt update
sudo apt upgrate
and when I restart the board there is not wifi device at all. The sudo ifconfig -a command does not show any wifi device at all anymore.
I have tried this already four to five times and I am pretty sure that something happens when I upgrade. Furthermore, after upgrade there is no hdmi output aswell I have to use the COM port.

Any help/tips?

I suppose this is the same issue as this one:

You can either update your bootimg or reflash your system and mark linux kernel hold for upgrade.


Thanks you for the quick response. This solution worked for me.
