Upgrade ESXi 4.1 to 5.x fails with error Downloading metadata failed.

I am trying to upgrade an ESXi 4.1 host to version 5.1 or 5.5. I tried updating it with PowerCLI and esxupdate. Below are the errors I am getting.

ESXUPDATE:
 esxupdate --bundle /vmfs/volumes/datastore1/ESXi-5.5.0-1331820-standard.zip update
error: Failed acquiring information for 'metadata-1284675570':

What you are trying to do from ESXi 4.1 to 5.1 is not supported, and does not work. BOOT server from CDROM and upgrade.

You cannot upgrade ESXi 4.1 to 5.1 using the depot bundle at the console, the supported method of upgrade is using the ISO CDROM, - Interactive upgrade from CD, DVD, or USB drive.
