Thank you for filing a bug and making Ubuntu and cloud-init better.
The reason you are unable to login as jpcozar is because the default
behavior of cloud-init is to lock password logins and prefer key-based
login for ssh.
What you'll need is to both allow password-based ssh logins with
"ssh_pwauth: true" and make sure the password is unlocked for jpcozar
with "lock_passwd: false".
the complete userdata below:
#cloud-config
ssh_pwauth: true
users:
- default
- name: jpcozar
groups: sudo
shell: /bin/bash
sudo: ALL=(ALL) NOPASSWD:ALL
passwd:
$6$ZE4Us0phF$/gVyOLzLIKI6uxCjYmkNnLxmtyZcicmZ8pXFTMM0P9TG14egqPDVm066uacHsuFw9vH1/i2fx5vTWpD/C//qc.

Title:
passwd: insert a blank space in /etc/shadow
Status in cloud-init:
Invalid
Bug description:
Hello,
I am using multipass 1.8.0.+win with a config file called cloud-init.yaml. I
create my own user and insert the hash password of my user like that:
users:
- default
- name: jpcozar
groups: sudo
shell: /bin/bash
sudo: ALL=(ALL) NOPASSWD:ALL
passwd:
$6$ZE4Us0phF$/gVyOLzLIKI6uxCjYmkNnLxmtyZcicmZ8pXFTMM0P9TG14egqPDVm066uacHsuFw9vH1/i2fx5vTWpD/C//qc.
Once multipass has created the virtual machine, I can't login with
user/passwd. If I check /etc/shadow, it inserts a blank space after
"<login>:" so I can't login.
jpcozar:
$6$ZE4Us0phF$/gVyOLzLIKI6uxCjYmkNnLxmtyZcicmZ8pXFTMM0P9TG14egqPDVm066uacHsuFw9vH1/i2fx5vTWpD/C//qc.:18961:0:99999:7:::
If I delete, such space, I can login
jpcozar:$6$ZE4Us0phF$/gVyOLzLIKI6uxCjYmkNnLxmtyZcicmZ8pXFTMM0P9TG14egqPDVm066uacHsuFw9vH1/i2fx5vTWpD/C//qc.:18961:0:99999:7:::
I have tried other options in cloud-init.yaml like
passwd:$6$ZE4Us0phF$/gVyOLzLIKI6uxCjYmkNnLxmtyZcicmZ8pXFTMM0P9TG14egqPDVm066uacHsuFw9vH1/i2fx5vTWpD/C//qc.
and it returns syntax error
or
passwd:
"$6$ZE4Us0phF$/gVyOLzLIKI6uxCjYmkNnLxmtyZcicmZ8pXFTMM0P9TG14egqPDVm066uacHsuFw9vH1/i2fx5vTWpD/C//qc."
and it generates such blank spaces.
