mprweb VS arch2appimage

Debian has the MPR https://mpr.makedeb.org/

https://mpr.makedeb.org/ this is the link.

I know the MPR is a thing, but I've always found it unwieldy to use.

So the main difference from something like MPR is that it does that same thing, but for more packages, not only .deb files?

Regarding system repositores, it's generally best to avoid tampering with system repositories like this because it'll cause problems with release upgrades down the line. But if you really want to, look into https://mpr.makedeb.org/ with the expectation that a release upgrade with these packages installed will most likely fail.

makedeb - Like makepkg, but produces installable *.deb files. There are already lots of packages in the MPR

Actually exists! https://mpr.makedeb.org/

Mist is powered by the MPR, an AUR-like repository that's also for Debian and Ubuntu based systems (of which I'm also the project lead for, as well as the makedeb project listed below). In short, it uses pretty much the same PKGBUILD format that you'd see on Arch Linux, but uses them to build .deb packages instead of Arch Linux packages.

Arch2AppImage is useless, just like my Arch-Deployer (Arch2AppImage is inspired by my project, see it's README), I've also created an "issue" on its repository to explain why I've abandoned it, see https://github.com/hanzala123/arch2appimage/issues/25 ).

I'm a creator of AppImage packages, the basis always used (and recommended) is to create them based on old distributions for compatibility reasons. With this solution I want to try to break that rule. Both my Arch-deployer and the better known arch2appimage failed at this (and were archived as a result).

less than two years ago I published a bash script that can that downloads a package from the Arch repository or from ChaoticAUR with all its dependences, and this was a big success for me on this community and on github. Later someone else, inspired by this project, have developed its own tool with a better code and easier to use (DT on YouTube did also a review on it, here). Everithing is great, I'm glad about all this, but... I stopped work on my repo more than 1 year ago (about december 2021) for a reason, the same that I think the developer of arch2appimage have understand later (and I said it into an issue, here), that's why its project have no more commits since 9 months. Arch-based AppImages are not a good idea, here are two reasons:

If you are in Arch, arch2appimage can easily make packages from Chaotic AUR.
