What version of Ansible are you using?

I also notice that there is some output related to Nvidia. Are you using additional playbooks or modified configuration?

Thank you for the good post.
I’m copying this post exactly the same, and I’m looking at this error.

[WARNING]: Unhandled error in Python interpreter discovery for host bastion: Failed to connect to the host via ssh:
kex_exchange_identification: Connection closed by remote host

TASK [kubespray-defaults : Gather ansible_default_ipv4 from ip-internal] **************************
fatal: [bastion]: UNREACHABLE! => {“changed”: false, “msg”: “Data could not be sent to remote host “IP”. Make sure this host can be reached over ssh: kex_exchange_identification: Connection closed by remote hostrn”, “unreachable”: true}

PLAY RECAP ***********************************************************************************************************
bastion : ok=6 changed=0 unreachable=1 failed=0 skipped=13 rescued=0 ignored=0

and I can’t find ssh-bastion.conf

How can I solve this problem?

Have you used the Master branch or one of the releases? Master branch is not really “stable” from time to time.

I have struggled a bit with this before stumbling on your post. Interesting that you did this only a month back. However, I continue to run into some errors down the line as below.

Did you make any changes to any of the YML files or any sort of changes to any file.
Thanks for your help.
