cloud-init error in opensuse

[Júlia]

When running cloud-init (version 21.4-150100.8.58.1) in an openSUSE 15.3 VM using NoCloud as datasource with the following configuration:

I am setting the meta-data file and user-data file in /var/lib/cloud/seed/nocloud/ directory.

meta-data file:

instance-id: intance-id
local-hostname: localhostname
hostname: hostname
dsmode: local

user-data file:

#cloud-config
write_files:
  - content: |
      "Does cloud-init work?"
    owner: root:root
    permissions: '0644'
    path: /srv/foo
  - content: |
      "IT SURE DOES!"
    owner: root:root
    permissions: '0644'
    path: /srv/bar

And the datasource information in /etc/cloud/cloud.cfg.d/10_datasource.cfg.

10_datasource.cfg file:

datasource_list: [ NoCloud, None ]

I am enabling the cloud-init services, rebooting the system and getting the following error:

Not sure why it's using debian.py instead of opensuse.py.

It looks like you have no /etc/cloud/cloud.cfg . If I launch a standard openSUSE 15.3 cloud image (using 'lxc launch images:opensuse/15.3/cloud'), I have this in /etc/cloud/cloud.cfg:
https://paste.ubuntu.com/p/CQn29SBTMj/

If I remove that file, I get the same traceback that you're seeing, so I think that should solve your issue. Given this, I'm going to set this bug as Invalid. If there's still a problem here that needs to be addressed, please do set it back to New.
