Panel: Package Manager Convergence: What Stands in the Way?
11-10, 16:00–16:45 (UTC), Room I

We’ve managed to bring all of you together from different package manager communities, but can we also bring the package managers you work on together? Is there room for one package manager to rule them all, or will package management always be a very domain-centric activity? If it does, is that good or bad?

We’ve brought together a panel of experts to hash this out! Please welcome:

  • Wolf Vollprecht (QuantStack, Mamba project, Condaforge)
  • Joshua Lock (VMWare, The Update Framework)
  • Ludovic Courtès (Inria, Guix project)
  • Andrew Nesbitt (Octobox,

Todd Gamblin (LLNL, Spack project) will moderate.

Each panelist will briefly give us their take on the following charge questions, followed by a lively discussion and questions from the audience.

  • Do you think there are too many package managers? Why or why not?
  • What parts of packaging could eventually be automated or replaced by infrastructure?
  • What parts of package managers do you think could be shared as common components? What would it take to make that happen?
  • If not through common components, what other ways could the many different packaging communities come together in the future?
  • What do we need to do to get people outside the packaging community to better understand these challenges?

Wolf Vollprecht is a Technical Director at QuantStack. QuantStack is a small open source software consulting company that mostly works on scientific open source software.
Wolf spends most of his time working on the mamba package manager, and as part of the conda-forge core team. Mamba is a fast, cross-platform and language agnostic package manager that works with conda packages.

Almost yen years ago, Ludovic started work on GNU Guix. It has since become the home of a vibrant community encompassing free software enthusiasts, principled developers, and scientists in search of reproducibility.

Before that, Ludovic was already a co-maintainer of GNU Guile, an implementation of the Scheme functional programming language, and a contributor to Nix, Nixpkgs, and NixOS—the beginning of a delightful journey at the crossroads of functional deployment and embedded domain-specific languages.
