Raspberry Pi 4 B refuses SSH connection #235

Closed kristjanp28 closed 4 years ago

kristjanp28 commented 4 years ago

Refuses SSH connection in AP mode or connected to the network. Tried creating SSH file in BOOT partition.

Im having the exact issue. Im trying to ssh into my raspberry pi 4 from my ubuntu machine and its stating the password is incorrect.

karpandrew12 commented 4 years ago

I ended up figuring out how to fix this. Before i tried ssh from development computer to robot comp with ssh pi@ipaddress. This was incorrect. The correct way is to ssh the name of your system in replacement to "pi". For example : ssh ubuntu@ipaddress.

I hope this helps.

There is no issue with wrong password. There is an issue with Pi itself or with the network that we are using.

Closing this because we found out that the issue was the ssh systemd service being configured badly.

@rohbotics should we update the image? Or could you give some hint hot to fix it on our existing image? I have the same issue, but my fix is to wait about 5-10 minutes :)

@an-dr The fix is here: https://forum.ubiquityrobotics.com/t/ros-image-on-raspberry-pi-4/326/59?u=rohbotics

It will be in the next image once we release that.
