We had the same issue. This fix it for us.. We deployed this fix on more than one of our upgrades and after the upgrade went just fine.
Log into vCenter as Administrator@vSphere.local the go to Administration - Roles It the Green + to add a new role.
** You MUST name the role (com.vmware.Content.Admin) plus check all the items under Content Library
Reboot your vCenter and try the upgrade again.
Many thanks! This was actually the problem!
