Cannot login in Ubuntu server 20.04 with RaspberryPi 4

Have followed instructions (endlessly) to load 20.04 (server only, no desktop or gui) on a RP4 w/8GBs of ram. Always the same result. On installation (first boot) I go into an endless loop at login.

Have searched the web for solutions and nothing seems to work except that I see this is a common situation.

I’m asked for ubuntu login:. I enter ubuntu. I’m asked for password. I enter ubuntu. I’m answered with

Login incorrect
ubuntu login:

If I could get past the loop I’d be ready for sudo apt update && sudo apt upgrade. But the loop, the endless loop, it won’t go away ....

Problem solved. Thank you Wayne .... your answer got me part way there.

  1. I used a new SD card. Don’t know if that made a difference or not.
  2. I connected to internet through Ethernet during the installation process. THAT made a huge difference. Instructions in the Ubuntu Server for Raspberry Pi tutorial say to use Ethernet OR to edit net-config for wireless. I initially went for the edit net-config option and the login loop was endless. Enter login name, enter password, over and over again.
  3. Connected to Ethernet as previously described, login worked as it should, and all is fine.
  4. The tutorial instructions probably need to be updated. Or maybe it was just my bad luck.

Hope this is helpful for someone .....
