PureOS consists of two archive sections, so-called "suites": **landing** and **green**.
Packages in the **green** suite are visible to the users of PureOS and are the current rolling release distribution.
The **landing** suite however contains packages not yet fit for being published in **green**.
Every package uploaded to PureOS needs to pass through **landing** before reaching **green**. Packages are automatically moved from **landing** to the release suite if they meet the following criteria:
* Contain no known bugs
* Are installable and do not make the target suite more broken. This includes:
- Being built on all main architectures
- Having dependencies available
- Being installable
* Have been in **landing** for at least a few hours
If everything is fine with your packages, you can be certain that it will be in green at least 18h after your upload (and most of the time 12h after your upload).
