4 cool new projects to try in Copr for December 2025

This article series takes a closer look at interesting projects that recently landed in Copr.

Copr is a build-system for anyone in the Fedora community. It hosts thousands of projects with a wide variety of purposes, targeting diverse groups of users. Some of them should never be installed by anyone, some are already transitioning into the official Fedora repositories, and others fall somewhere in between. Copr allows you to install third-party software not found in the standard Fedora repositories, try nightly versions of your dependencies, use patched builds of your favourite tools to support some non-standard use-cases, and experiment freely.

If you don’t know how to enable a repository or if you are concerned about whether is it safe to use Copr, please consult the project documentation.

4 cool new projects to try in Copr for August 2022

Copr is a build system for anyone in the Fedora community. It hosts thousands of projects for various purposes and audiences. Some of them should never be installed by anyone, some are already being transitioned to the official Fedora Linux repositories, and the rest are somewhere in between. Copr gives you the opportunity to install third-party software that is not available in Fedora Linux repositories, try nightly versions of your dependencies, use patched builds of your favorite tools to support some non-standard use cases, and just experiment freely.

If you don’t know how to enable a repository or if you are concerned about whether it is safe to use Copr, please consult the project documentation.

This article takes a closer look at interesting projects that recently landed in Copr.

Ntfy

Ntfy is a simple HTTP-based notification service that allows you to send notifications to your devices using scripts from any computer.

$ ntfy publish beer-lovers "Hi folks. I love beer!"
{"id":"4ZADC9KNKBse", "time":1649963662, "event":"message", "topic":"beer-lovers", "message":"Hi folks. I love beer!"}

And a listener who subscribes to this topic will receive:

Python-QT6

Do you miss QT6 Python bindings for Fedora Linux? Here they are. https://copr.fedorainfracloud.org/coprs/g/kdesig/python-qt6/

KDE SIG owns this project. Therefore, it should be a quality one. And one day, it may land in Fedora Linux.

Example of usage:

$ python Python 3.10.4 (main, Mar 25 2022, 00:00:00) [GCC 12.0.1 20220308 (Red Hat 12.0.1-0)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import PyQt6 >>> from PyQt6.QtWidgets import QApplication, QWidget >>> import sys >>> app = QApplication(sys.argv) >>> window = QWidget() >>> window.show() >>> app.exec() 0

These packages are available for Fedora 36 Linux and Rawhide. To install them, enter this command:

sudo dnf copr enable mroche/cloud-native-utilities

DNF 5

You may be aware the DNF team is working on DNF5. There is a change proposal for Fedora Linux 38. The benefit is that every package management software — including PackageKit, and DNFDragora — should use a common libdnf library. If you have an application that handles RPM packages, you should definitely check out this project.

https://copr.fedorainfracloud.org/coprs /rpmsoftwaremanagement/dnf5-unstable/

4 cool new projects to try in COPR from December 2020

COPR is a collection of personal repositories for software that isn’t carried in Fedora. Some software doesn’t conform to standards that allow easy packaging. Or it may not meet other Fedora standards, despite being free and open-source. COPR can offer these projects outside the Fedora set of packages. Software in COPR isn’t supported by Fedora infrastructure or signed by the project. However, it can be a neat way to try new or experimental software.

This article presents a few new and interesting projects in COPR. If you’re new to using COPR, see the COPR User Documentation for how to get started.

Come test a new release of pipenv, the Python development tool

Pipenv is a tool that helps Python developers maintain isolated virtual environments with specifacally defined set of dependencies to achieve reproducible development and deployment environments. It is similar to tools for different programming languages, such as bundler, composer, npm, cargo, yarn, etc.

A new version of pipenv, 2020.6.2, has been recently released. It is now available in Fedora 33 and rawhide. For older Fedoras, the maintainers decided to package it in COPR to be tested first. So come try it out, before they push it into stable Fedora versions. The new version doesn’t bring any fancy new features, but after two years of development it fixes a lot of problems and does many things differently under the hood. What worked for you previously should continue to work, but might behave slightly differently.

How to get it

If you are already running Fedora 33 or rawhide, run $ sudo dnf upgrade pipenv or $ sudo dnf install pipenv and you’ll get the new version.

On Fedora 31 or Fedora 32, you’ll need to use a copr repository until such time comes that the tested package will be updated in the official place. To enable the repository, run:

$ sudo dnf copr enable @python/pipenv

Then to upgrade pipenv to the new version, run:

$ sudo dnf upgrade pipenv

Or, if you haven’t installed it yet, install it via:

$ sudo dnf install pipenv

In case you ever need to roll back to the officially maintained version, you can run:

$ sudo dnf copr disable @python/pipenv
$ sudo dnf distro-sync pipenv

COPR is not officially supported by Fedora infrastructure. Use packages at your own risk.

How to use it

If you already have projects managed by the older version of pipenv, you should be able to use the new version in its place without issues. Let us know if something breaks.

If you are not yet familiar with pipenv or want to start a new project, here is a quick guide:

Create a working directory:

$ mkdir new-project && cd new-project

Initialize pipenv with Python 3:

$ pipenv --three

Install the packages you want, e.g.:

$ pipenv install six

Generate a Pipfile.lock file:

$ pipenv lock

Now you can commit the created Pipfile and Pipfile.lock files into your version control system (e.g. git) and others can use this command in the cloned repository to get the same environment:

$ pipenv install

See pipenv’s documentation for more examples.

How to report problems

If you encounter any problems with the new pipenv version, please report any issues in Fedora’s Bugzilla. The maintainers of the pipenv package in official Fedora repositories and in the copr repository are the same. Please indicate in the text that the report is regarding this new version.
