I am trying to install Ubuntu 20.10 on my raspberry Pi 4 8Gb RAM using a 16 Gb SD card. I have followed this tutorial exactly. I have tried to install it using wlan0 or eth0 by modifying the network-config file as:

#ethernets:
  eth0:
    dhcp4: true
    optional: true
#wifis:
  wlan0:
    dhcp4: true
    optional: true
    access-points:
      "My network":
    password: "My password"

but I am always getting stucked at the cloud-init point. I am getting exactly this: enter image description here

It hangs on until I press enter. Then I get to the login prompt but I can't log in as I type "ubuntu" for both login and password, it returns: "incorrect password". I have seen answers saying to try to ssh into the pi, but I don't get it as my Pi doesn't even have an fixed IP address. So my question is: how should I get over it ? I am completely blocked at that point.

I have also tried other versions as I would initially prefer ubuntu 18.04, but I wasn't able to find any desktop version, and the server version I found doesn't boot properly. My raspberry simply considers there is no SD card

Any help or hint would be much appreciated. Thank you very much

  • FWIW, I'm having this error even without modifying the network-config file, and I've tried user-data files that work on other pis. This is frustrating. – weberc2 Oct 15 '21 at 15:04
  • @weberc2 As far as I can remember, I had an error in the config file. I think there was a space or a tab not in the right place. Be really carefull how you write it. What I had done to "debug" it was removing litterally all elements, until it worked. If necessary, I can find my config file back if you really need it – Joachim Bsh Oct 15 '21 at 15:58
  • I guess I don't know why I would have an error... I haven't touched that file. As far as network-config goes, I'm using whatever file comes with the stock ubuntu image. I've only touched user-data. – weberc2 Oct 15 '21 at 16:06

If the cloud functionality is not required, the cloud-init process can be deactivated!

To do this, the following file must be created:

sudo touch /etc/cloud/cloud-init.disabled
sudo reboot

Result in /etc/cloud/:

-rw-r - r-- 1 root root 0 May 19 11:09 pm cloud-init.disabled

If you delete the empty file, cloud-init is started during the boot process again. I hope this helps.

So after L O N G hours of trying to understand what was going on, I finally got it working. The error was in the network-config file. I had a symbol which was not marked as a comment and hence the cloud-init was not starting correctly because the network-config file had threw an error. However this is NOT mentionned in any status ! There is only a warning. So be extremely carefull at how your network-config file is written. If there is an error there, the cloud-init doesn't boot correctly, and for some reason, both ubuntu login and password are not accepted.

There are actually several causes that can result in the ubuntu login loop, see this answer for a more comprehensive list of how to fix it. In my case, the home directory permissions were changed to read-only.
