Restore or Replication job fails with "Error: Sequence contains more than one matching element." (4033823)

A restoration or replication job fails with the following error in the user logs: "Error: Sequence contains more than one matching element."

Example of Task Logs are as follows:

For Restore Jobs:
Creating virtual machine 'vm_name' completed.
Error: Sequence contains more than one matching element.

For Replication Jobs:
Creating virtual machine 'vm_name_Replica' completed.
Removing snapshot for vRanger completed.
Error: Sequence contains more than one matching element.

There are two causes for this issue:

1. Missing permissions on the non-administrative Virtual Center account.
2. Two network elements in vCenter share the same name. vRanger pulls elements from the Network Inventory using their names. Since vCenter server does not assign unique identifiers to its network elements, this cause that network elements with the same name cannot be differentiated.

In order to resolve this issue:

1. Make sure that your vRanger account has an Administrator Role in vCenter or has the minimum permissions as specified by the knowledge article KB116724. 
2. In vCenter's "Networking" inventory, rename one of the elements with duplicated name. These networking elements can be (but not limited to) VM Networks, Port Groups, Standard Switches, and Distributed Switches.

NOTE: If your vCenter account already contains the minimum required permissions and the network elements in your environment cannot be renamed, try the following workarounds:

• Restore or Replicate to a cluster where the hosts do not have network elements with the same name.
• In vCenter create a dummy VM with the same settings (CPU, RAM, Disks, etc) and then, in vRanger check the option "Force Overwrite" in the Restore Wizard.
