How do I install a Linux image (https://cloud-images.ubuntu.com) in MicroStack (https://ubuntu.com/tutorials/microstack-get-started#2-install-microstack)? This question is close: How to install packages in cirros OS. But doesn't share the command that is needed. For example, I've tried the following:
microstack launch cirros --name test
The above works, but can't use it as it has no packages. So unusable.
So I tried the following, nothing is working
microstack launch ubuntu --name test
microstack launch debian --name test
microstack launch focal --name test
Second, I've download the a ubuntu ISO. And attempted to upload the image under Compute > Images. While it uploads in the GUI of OpenStack aka Horizon. The following error happens: "Flavor's disk is too small for requested image."
