Comment 6 for bug 1615875

I had a similar problem.

In my case, the error message is as follows:
"The OVF package is invalid and cannot be deployed."
"The following manifest file entry (line 1) is invalid: SHA256(ubuntu-xenial-16.04-cloudimg.vmdk ..."

I tried to edit the ova file as above (bios -> efi). BUT, it is not worked for me.

I solved this problem by using VMware OVF Tool with "--skipManifestGeneration" as follows.

---------------------
c:\Users\<myhome>\Downloads>"C:\Program Files\VMware\VMware OVF Tool\ovftool.exe" --skipManifestGeneration -o "ubuntu-16.04-server-cloudimg-amd64.ova" "ubuntu-16.04-server-cloudimg-amd64-skipManifestGeneration.ova
Opening OVA source: ubuntu-16.04-server-cloudimg-amd64.ova
The manifest validates
