# Unsupported distribution or misconfigured repository settings

If you are seeing this message, it may mean that your are using an [unsupported distribution](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html#linux-distributions).

It may also mean that your repositories are incorrectly configured.

In order to simplify the release process for the NVIDIA Container Toolkit and its components, we rely on a set of reference repositories which can be used across a number of distributions. The main references repositories and their compatible distributions are (this is not a complete list):

## Generic .deb package repository

### Compatible with

Most distributions that use DEB packages. These include:

* Ubuntu
* Debian

### Repository list URLs

* `https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list`
* `https://nvidia.github.io/libnvidia-container/experimental/deb/nvidia-container-toolkit.list`

### Repository roots

* `https://nvidia.github.io/libnvidia-container/stable/deb`
* `https://nvidia.github.io/libnvidia-container/experimental/deb`

## Generic .rpm pakcage repository

### Compatible with

Most distributions that use RPM packages. These include:

* RHEL
* Fedora

### Repository file URLs

* `https://nvidia.github.io/libnvidia-container/stable/rpm/nvidia-container-toolkit.repo`
* `https://nvidia.github.io/libnvidia-container/experimental/rpm/nvidia-container-toolkit.repo`

### Repository roots

* `https://nvidia.github.io/libnvidia-container/stable/rpm`
* `https://nvidia.github.io/libnvidia-container/experimental/rpm`

## GitHub Pages repository structure

The packages here are served from the [`gh-pages` branch](https://github.com/NVIDIA/libnvidia-container/tree/gh-pages/) of the
`github.com/NVIDIA/libnvidia-container` repository. The repository folder structure maps directly to the package manager URLs.

For example, the repositories discused above can be found at:
* `stable/deb`: https://github.com/NVIDIA/libnvidia-container/tree/gh-pages/stable/deb
* `experimental/deb`: https://github.com/NVIDIA/libnvidia-container/tree/gh-pages/experimental/deb
* `stable/rpm`: https://github.com/NVIDIA/libnvidia-container/tree/gh-pages/stable/rpm
* `experimental/rpm`: https://github.com/NVIDIA/libnvidia-container/tree/gh-pages/experimental/rpm

This also means that packages can be downloaded directly by appending the package filename to the following URLs:
* `https://raw.githubusercontent.com/NVIDIA/libnvidia-container/gh-pages/stable/deb/amd64/`
* `https://raw.githubusercontent.com/NVIDIA/libnvidia-container/gh-pages/experimental/deb/amd64/`
* `https://raw.githubusercontent.com/NVIDIA/libnvidia-container/gh-pages/stable/rpm/amd64/`
* `https://raw.githubusercontent.com/NVIDIA/libnvidia-container/gh-pages/experimental/rpm/amd64/`
