VUM error during remediation of ESXi host upgrade from 5.1 to 5.5:
“vmware update manager 5.5 Cannot run upgrade script on host“
Debugging the problem:
Troubleshooting this problem led to a few discoveries online of users experiencing the same error message but different log entries regarding problem. This can be read in kb articles below:
I tried with the VMware rollup ESXi as well as the Dell provided iso and had the exact same problem.
After the upgrade fails, SSH to your ESXi host and look for the following entries in \var\log\vua.log

I opened a case with VMware to get this resolved so if you experience the same problem I do recommend contacting VMware support to further assist. If you intend to use this fix, please do so at your own risk.
To fix this issue, manually remove the FDM agent on the host, reboot and retry the upgrade.
Note: Removing the host from a vSphere HA cluster also removes the agent. If the agent is not removed, you may have to manually remove the agent.
To manually remove the FDM agent from the host, run these commands:
cp /opt/vmware/uninstallers/VMware-fdm-uninstall.sh /tmp
chmod +x /tmp/VMware-fdm-uninstall.sh
Reboot the host
After the FDM agent is removed and host has been rebooted you can run the remediation again for host upgrade.
