Standard Raspberry pi 4
It downloaded a huge system update after:
"sudo apt upgrade"
after reboot and WD restart - no uploads anymore...

Ubuntu 20.04 on my laptop don't work either... Numpy doesn't install (but the Laptop with Ubuntu 20.04) is a different story to be solved seperately

I keep the raspberry running - so you might look at it, if the power failure will be solved... (password unchanged)
