• In the vCenter Appliance Management (VAMI):
  
  "Package discrepency error, Cannot resume!"

Environment

Resolution

Note:

• If the default shell was changed to /bin/bash, use /bin/appliancesh to enter the Appliance-Shell.
• Ensure you have a working backup before attempting to update vCenter. 

Follow the steps below:

1. Log in to vCenter via SSH.
2. Run the following command:
   
   software-packages unstage
   
   
3. Start the update process again.

If the above steps do not resolve, follow the steps below. Important: Ensure you have a proper backup or offline snapshot before applying the steps below.

1. SSH to vCenter via root
2. Stop the appliance management service:
   
   service-control --stop applmgmt
   
   
3. Remove the following:
   
   rm -rf /storage/core/software-update/updates/*
rm -rf /storage/core/software-update/stage/*
rm -rf /storage/db/patching.db
   
   Note: In some scenarios, if vCenter uses /storage/seat partition to store the software update, you may need to remove the following as well:
   
   rm -rf /storage/seat/software-*
   
   
4. Move the following files to /storage/core:
   
   mv /storage/core/software-packages/staged-configuration.json /storage/core
mv /etc/applmgmt/appliance/software_update_state.conf /storage/core
   
   
5. Start the appliance management service:
   
   service-control --start applmgmt
