Technical Note: Unable to distribute code to pods from NCM UI
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
>ssh FN600.mycompany.net
The authenticity of host 'FN600.mycompany.net (10.2.10.113)' can't be established.
ECDSA key fingerprint is SHA256:/WQrPV2UCK6To7De6HFb+vpMwNoH5rO86VGefzJWaWM.
ECDSA key fingerprint is MD5:c8:fd:29:4a:6a:a5:0c:81:ec:54:4f:d7:30:3f:8f:02.
Are you sure you want to continue connecting (yes/no)?
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.

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

Are you sure you want to continue connecting (yes/no)?
The prompting interrupts the connection and causes the code distribution to fail.
3. Logout and re-attempt SSH connection to verify connection completes without prompting for additional input.
4. Re-attempt code distribution from NCM UI.
