Technical Note: Unable to distribute code to pods from NCM UI

[cmaheu]

Description
Code distribution from the NCM UI (System > Settings > Updates > System) to one or more managed pods fail with the following message:

<FQDN> error code 500


Example:
FN600.mycompany.net error code 500


Solution
1.  From NCM CLI, SSH to FQDN to validate SSH connection.

Example:
ssh FN600.mycompany.net

The following example prompts for a response because the FQDN (FN600.mycompany.net) is not in the NCM's known_hosts file

>ssh FN600.mycompany.net
The authenticity of host 'FN600.mycompany.net (10.2.10.113)' can't be established.

Are you sure you want to continue connecting (yes/no)?

The prompting interrupts the connection and causes the code distribution to fail.

2.  Answer "yes" and the name will be added, completing the connection.

3.  Logout and re-attempt SSH connection to verify connection completes without prompting for additional input.

4.  Re-attempt code distribution from NCM UI.
