Environment

VMware vCenter Update Manager 6.7.x

Cause

This issue occurs due to the replication appliance pushing the VIBs due to which we get the error "Another task is in progress"

Resolution

To resolve this  issue please follow the below steps:-

1. Take a putty session to the Replication Appliance and run the below commands,
   • /opt/vmware/hms/bin/hms-configtool -cmd reconfig -property hms-auto-install-vr2c-vib=false
   • /opt/vmware/hms/bin/hms-configtool -cmd reconfig -property hms-auto-install-hbragent-vib=false
   • service hms restart
2. After the changes go to Update Manager and run the scan and remediate the ESXi host
