Environment

VMware vCenter Server 6.7.x
VMware vCenter Server Appliance 6.5.x

Cause

This issue occurs when the VCSA does not have internet connectivity.

Resolution

To solve the issue, follow the steps given below:

1. Delete all content from in the VCSA folder /var/log/vmware/converge by running:

rm -rf /var/log/vmware/converge/*;

2. Delete the file task.json from the VCSA:

rm /root/velma/task.json;

3. Reboot the external PSC and confirm all services started using the command: 

service-control --status --all;

4. Reboot the VCSA. 
5. Download the vCenter Server Appliance 6.7 Update 2 ISO image.From the VMware website at https://customerconnect.vmware.com/web/vmware/downloads,

   VMware-VCSA-all-version_number-build_number.iso

6. Confirm that the md5sum is correct.

   See the VMware website topic Using MD5 Checksums at http://www.vmware.com/download/md5.html.

7. Attach the ISO image to the CD/DVD drive of the VCSA.
8. Mount the ISO to the /mnt/cdrom folder with command: 

mount /dev/cdrom /mnt/cdrom;

9. Try converting to Embedded VCSA using the Converge tool again.
