Image and version of the image where the issue happens

Ubuntu 18.04

Describe the bug

I finally got around to trying to merge https://github.com/containers/toolbox/pull/483 to offer built-in support for Ubuntu, when I noticed that compared to the ubuntu-toolbox image for other versions, the ubuntu-toolbox:18.04 image is substantially smaller. As per skopeo inspect it's 68.98MB, while the others are approximately 160MB.

I haven't checked if something is wrong or broken, but the size difference jumped out at me.

Reproduction steps

With Toolbx from Git main:

[rishi@topinka toolbox]$ toolbox create --image quay.io/toolbx-images/ubuntu-toolbox:18.04
Image required to create toolbox container.

After some more testing, I see that the ubuntu-toolbox:18.04 image leads to a container that can't be entered because capsh(1) is missing. See https://github.com/toolbx-images/images/issues/73

Thanks for testing it. I'm not sure we'll do more if it works like that. 18.04 is too old now.

It appears the issue is that 18.04 Containerfile is due to missing ubuntu-minimal, ubuntu-standard for some reason (instead it's in the FIXME - I have no idea why). And apparently that's the reason we experience #73 and consequently #74 is not required. Opened #75.

The Git history says that /usr/local/sbin/unminimize, ubuntu-minimal and ubuntu-standard were removed from ubuntu-toolbox:18.04 in commit 5cbaecde2f30ea1d to fix the build.
