When you are trying to upgrade the VMware Cloud Director (VCD) to 10.6.x you get the below error:Failure: Error downloading manifest. Please contact your vendor. URL rejected: No host part in the URL URL: /opt/vmware/vcloud-director/data/transfer/update/manifest/manifest-latest.xml
VMware Cloud Director 10.6.x
The issue happens because you did not provide the correct path for local-update-package directory as the update repository.
For workaround use the correct path to set the local-update-package directory as the update repository. For example: vamicli update --repo file:///tmp/local-update-package
Please follow the document for upgrading To VMware Cloud Director 10.6.x properly: Upgrading To VMware Cloud Director 10.6.x
