NonGNU Elpa Package Repository

Hello, I have the following package settings in my init.el (require 'package) (setq package-archives '(("melpa" . "https://melpa.org/packages/") ("org" . "https://orgmode.org/elpa/") ("gnu" . "https://elpa.gnu.org/packages/"))) (package-initialize) Do I need to add anything else to enable the NonGNU ELPA Packages introduced in Emacs 28.1? I heard the NonGNU ELPA is enabled by default in Emacs but I guess my config excludes it. Right?

I suggest using `add-to-list` to add only the non-default things, rather than clobbering the entire list.

Your configuration is excluding it, as you redefine the variable, which indeed includes it by default. You need to use `add-to-list` to not override the variable, or redefined it with all package archives. Here's mine: (setq package-archives '(("MELPA" . "https://melpa.org/packages/") ("MELPA Stable" . "https://stable.melpa.org/packages/") ("GNU ELPA" . "https://elpa.gnu.org/packages/") ("NonGNU ELPA" . "https://elpa.nongnu.org/nongnu/")) package-archive-priorities '(("MELPA" . 8) ("MELPA Stable" . 6) ("GNU ELPA" . 4) ("NonGNU ELPA" . 10))) As you can see, you need to add the [`https://elpa.nongnu.org/nongnu/`](https://elpa.nongnu.org/nongnu/) URL for having the NonGNU ELPA archive. Please, note that the [Org ELPA](https://orgmode.org/elpa.html) (with URL [`https://orgmode.org/elpa/`](https://orgmode.org/elpa/)) is [deprecated since Org-Mode v9.5](https://orgmode.org/Changes.html).

Is there anything wrong in using the `package-archives`? If I use `add-to-list` as you suggested, then I need to use a conditional for Emacs 27 to add the non gnu repo to the list. However, if I use the variable to define all the repos as I did above, they will be applied to both Emacs 27 and 28.

Thank you! Isn't it better to install from GNU first, then Non GNU? and leave the Melpas at the end?

`add-to-list` will not add duplicate entries.

The chance of getting duplicate entries is little to zero. I only have a list of 4 repos which is not going to be altered once set.

Sorry, I think I misunderstood your issue with using `add-to-list`.

I think it depends on what do you expect, it's a matter of choice. Note that it will not change anything for packages that are available in only one of the archives. For packages present in at least 2 archives, MELPA seems to be more up-to-date, and GNU more stable for old versions of Emacs. Acceptance criteria also differ between different archives.

The point being you *don't* "need to use a conditional" for Emacs 27, *because* `add-to-list` won't add duplicates; and if some future version of Emacs adds yet another default archive, your config won't then be clobbering that by default. But it's up to you; my suggestion was merely a suggestion.
