It's impossible to move two major-versions forward when upgrading Nextcloud. This is an issue when comming from 19.09 (using Nextcloud 16) and trying to upgrade to 20.03 (using Nextcloud 18 by default). This patch implements the measurements discussed in #82056 and #82353 to improve the update process and to circumvent similar issues in the future: * `pkgs.nextcloud` has been removed in favor of versioned attributes (currently `pkgs.nextcloud17` and `pkgs.nextcloud18`). With that approach we can safely backport major-releases in the future to simplify those upgrade-paths and we can select one of the major-releases as default depending on the configuration (helpful to decide whether e.g. `pkgs.nextcloud17` or `pkgs.nextcloud18` should be used on 20.03 and `master` atm). * If `system.stateVersion` is older than `20.03`, `nextcloud17` will be used (which is one major-release behind v16 from 19.09). When using a package older than the latest major-release available (currently v18), the evaluation will cause a warning which describes the issue and suggests next steps. To make those package-selections easier, a new option to define the package to be used for the service (namely `services.nextcloud.package`) was introduced. * If `pkgs.nextcloud` exists (e.g. due to an overlay which was used to provide more recent Nextcloud versions on older NixOS-releases), an evaluation error will be thrown by default: this is to make sure that `services.nextcloud.package` doesn't use an older version by accident after checking the state-version. If `pkgs.nextcloud` is added manually, it needs to be declared explicitly in `services.nextcloud.package`. * The `nixos/nextcloud`-documentation contains a "Maintainer information"-chapter which describes how to roll out new Nextcloud releases and how to deal with old (and probably unsafe) versions. Closes #82056
Nixpkgs is a collection of over 40,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- Nix RFCs - the formal process for making substantial changes to the community

Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 19.09 release
- Tests for unstable/master
- Tests for the NixOS 19.09 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem a lot at first, it helps consider it in the context of the scope of the project. Nixpkgs describes how to build over 40,000 pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests. When pull requests are made, our tooling automation bot, OfBorg will perform various checks to help ensure expression quality.
The Nixpkgs maintainers are people who have assigned themselves to maintain specific individual packages. We encourage people who care about a package to assign themselves as a maintainer. When a pull request is made against a package, OfBorg will notify the appropriate maintainer(s). The Nixpkgs committers are people who have been given permission to merge.
Most contributions are based on and merged into these branches:
masteris the main branch where all small contributions gostagingis branched from master, changes that have a big impact on Hydra builds go to this branchstaging-nextis branched from staging and only fixes to stabilize and security fixes with a big impact on Hydra builds should be contributed to this branch. This branch is merged into master when deemed of sufficiently high quality

The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.
