Very good tutorial, but I was not able to boot my raspberry pi.
I am using Pi Imager to install Ubuntu 20.04 LTS OS on an SD card. Then I plug the card into my Pi and try to log in to my Raspberry Pi 4 via SSH using the Putty software in Windows 10 (I am using wifi and trying to make an ssh connection.).
I used the IPv4 address as Host Name, and the command prompt opens. But I have an “access denied” problem when I inserted “ubuntu” as the username and password.
I have tried with different SD cards, but still, this issue exists.
Is there anyone with the same issue?
Thank you for your help.
