Environment

AWS
TKGI

Cause

If the stemcell is uploaded to opsman using the cp command, the stemcell will be extracted in the following format.
 

ubuntu:~$ sudo ls -ltr /var/tempest/stemcells/

tempest-web tempest-web 4566y77 Mar 31 07:20 light-bosh-stemcell-1.682-aws-xen-hvm-ubuntu-jammy-go_agent.tgz

Opsman expects the following format.

light-bosh-aws-xen-hvm-ubuntu-jammy-go_agent-1.682.tgz

 

Resolution

There are 2 methods to upload the stemcell.

1) Import the stemcell directly from the opsman UI.

2) upload the stemcell using OM cli.

om -e  upload-stemcell -s filename

These two methods are both capable of extracting stemcells in the correct format.
