Error: "File name does not conform to the expected format..." when uploading pub file to NSX to NSX Manager.

Products

• VMware NSX

Issue/Introduction

• You are upgrading NSX Manager.
• You are attempting to upload the pub file to NSX Manager.
• Once you select the file, NSX Manager throws an error:

  File name does not conform to the expected format. Please remove extra characters such as brackets and try again

  

Environment

VMware NSX-T Data Center 3.x

Cause

NSX-T 3.x supports only the .MUB file. 
The .PUB files were added to the upgrade workflow in later releases (VMware NSX 4.x)

Resolution

Download the correct MUB upgrade bundle from the Broadcom Customer Support Portal.
Upload and use the MUB file, as it contains both the upgrade prechecks and the upgrade software.
