New setup but not create image

I installed the Minione. After 5 minutes, I wanted to create an image by following this video.

but I am getting an error as below. There are two “/ /” signs, I think the script installation in the repo is doing it wrong. I did the installation on ubuntu focal.


Can you post the full error log ?

my setup input
Path in OpenNebula server or URL

this full error log.

That video was made on an old version of OpenNebula, if you are interested in using images from dockerhub, we actually have it integrated as a marketplace. You will get on top the benefits of an auto-contextualized image.

In fact, the reason for using opennebula is to make it easy to manage firecracker machines. If there is an explanation in the rootfs creation section for Firecracker, I can look there as well.

Hi @Nurullah_CALISKAN,

It seems your URL is not properly build, you’re using:


Note that you’re setting the tag as name:tag. If you take a look at the official documentation you have to pass the tag as an URL argument:


As @dclavijo said, the video is based on and old version of OpenNebula, so the format used differs with the current implementation.
