default password not set

[Heinrich Schuchardt]

I wrote http://cdimage.ubuntu.com/ubuntu-server/focal/daily-preinstalled/20220223/focal-preinstalled-server-riscv64+unmatched.img.xz to SD card.

SiFive Unmatched reaches boot prompt.

After these messages

login with ubuntu:ubuntu is still not possible.

Error message: "Login incorrect"

Running the same image on QEMU does not show the problem.

Something was written to passwd and shadow on the SD-card:

-rw-r--r-- 1 root root 1709 Feb 23 15:49 passwd
-rw-r----- 1 root shadow 1007 Feb 23 15:50 shadow

# tail shadow -n1

openssl passwd -6 -salt lzpbaYZrxSzzTfyF
Password: ubuntu
$6$lzpbaYZrxSzzTfyF$6H75QX0fpKIMf6wc80qSl0/YDJiHZwHGvO.opjOs5zfKhwfbdr0no2KqT2dOG2hc6rr7UOoquj3xPCzyhH4n51

So the password set was not ubuntu.

This is really weird, thanks for reporting. Is this reproducible everytime?

I have failed to recreate this locally.

By default, server images don't set a default user/password. Cloud-init will create the ubuntu user, but expects SSH auth by default and so will lock the password for the ubuntu user. Did you use an installer with the image? Was any userdata included on the SD card that you know of?

If you can access the instance, can you run cloud-init collect-logs and attach the tarball here? If not, can you grab /var/log/cloud-init.log, /var/log/cloud-init-output.log, and the contents of /etc/cloud and attach them here?

@Heinrich is it possible that this bug is a duplicate of the following: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/2013403

which shows that cloud-init hadn't yet processed user-data setting up the user credentials yet.
