So it depends on the host and how they are named and was really a test case. The one I’m really concerned about is this one now

{% for host in groups[‘servers\_production’] %}  
{{ hostvars[host][‘ssh\_host\_key\_ecdsa\_public’] }}  
{% endfor %}

I think you mean: hostvars[host]\*['ansible\_facts']\*['ssh\_host\_key\_ecdsa\_public']

This works for me and prints the key.---  
- hosts: all

tasks:  
- debug:  
msg: "{% for host in groups['all'] %} {{ hostvars[host]['ansible\_facts']['ssh\_host\_key\_ecdsa\_public'] }} {% endfor %}"

Please post the play you're using, or at least the relevant task and template.

What version are you running? The linux host is centos7.6

Verified in my facts

“ansible\_ssh\_host\_key\_ecdsa\_public”: “AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBGpMZqjhIzo6gGjz4eczxnatrAgmPxdWVYf0zY29MDngkKuOzjB0bMrR5sQm1X6leGgYowv3wNloWOZVbhwPU2A=”,

Your version has double quotes around the second line. The known working version does not. Could that be an issue?

I removed it with the same issue

{% for host in groups[‘all’] %}  
{{ hostvars[host][‘ansible\_facts’][‘ssh\_host\_key\_ecdsa\_public’] }}

This template also works for me, and the keys are different. So you might want to try it:

{% for host in groups[‘all’] %}  
{{ hostvars[host][‘ansible\_ssh\_host\_key\_ecdsa\_public’] }}  
{% endfor %}

Same error, can you send full playbook details over you are testing?

Can you try removing the "

ignore\_errors: yes  
"you had before? Maybe something in failing in the facts gathering and, naturally, the variables did not get populated.

Here’s the full playbook and template I used to test (this does not even need to escalate privileges):

Getting this now.

I debug the facts and see it
