May I convince you to be the maintainer of these Ubuntu images? :)

Probably not, I only use Centos and Fedora. Debian and its derivatives aren't anything I work with normally. I really just did this one as a demonstration.

Ok.

Before we announce support for Ubuntu, we would need somebody who cares enough about Ubuntu to ensure that Toolbox keeps working on a day to day basis with Ubuntu hosts and images. I am a little apprehensive of taking up that responsibility myself. I could, but it seems wise to spread the load around a bit.

Anyway, in the meantime, we can work towards removing the rough edges before thinking of making any announcements. :)

Sounds good to me.

[Toolbox](https://github.com/debarshiray/toolbox) is a tool that offers a
familiar RPM based environment for developing and debugging software that runs
fully unprivileged using [Podman](https://podman.io/).

The toolbox container is a fully *mutable* container; when you see
`yum install ansible` for example, that's something you can do inside your
toolbox container, without affecting the base operating system.

This is particularly useful on
[OSTree](https://ostree.readthedocs.io/en/latest/) based Fedora systems like
[Silverblue](https://silverblue.fedoraproject.org/). The intention of these
systems is to discourage installation of software on the host, and instead
install software as (or in) containers.

However, this tool doesn't *require* using an OSTree based system — it
works equally well if you're running e.g. existing Fedora Workstation or
Server, and that's a useful way to incrementally adopt containerization.

The toolbox environment is based on an [OCI](https://www.opencontainers.org/)
image. On Fedora this is the `fedora-toolbox` image. This image is used to
create a toolbox container that seamlessly integrates with the rest of the
operating system.

## Usage

### Create your toolbox container:
```
[user@hostname ~]$ toolbox create
Created container: fedora-toolbox-30
Enter with: toolbox enter
[user@hostname ~]$
```
This will create a container called `fedora-toolbox-<version-id>`.

### Enter the toolbox:
```
[user@hostname ~]$ toolbox enter
⬢[user@toolbox ~]$
```

I am curious. Did you check that these packages are the ones missing from the Ubuntu base image that are necessary to replicate the command line user experience on a usual Ubuntu host?

To be honest, I am not sure what's the most future-proof option here. We started off by trying to replicate the default Fedora Workstation/Silverblue CLI UX in the Toolbox images. However, now that we are adding other distributions, and supporting different variants of Fedora other than Silverblue and Workstation, I don't know what a freshly created container should have.

That's part of the reason I don't want to maintain the Ubuntu toolbox image. I don't actually use the distribution, so I can't say what a "usual" user experience would be for it.
