So the thing with Debian and any Debian based distro like Ubuntu or Linux Mint is there is no big centralized software repo like the AUR. Yes there is the apt repository but if you want something that’s not in there, get ready to read the documentation or follow random guides.
For example, one of my friends wanted to download an audio tool called Reaper. On Windows this is just looking up the application and clicking on the .exe. It really depends on the dev if they include a .deb, sometimes you might need to download the .sh file or they may tell you to compile it yourself. Perhaps, you have to add a ppa. On Arch, all I have to do is Paru -S Reaper, if there are multiple Reapers I can look for that by typing Paru Reaper.
Now that Arch is so easy to install with the Archscript, and the software repo so vast and easy to use, is Debian really user friendly if you have to jump through several hoops to download programs?
Edit: yeah yeah there’s flathub and stuff but that’s more of a last resort, optimally, you want to get it the correct way.
So then you’re saying the debian community sees value in something like the aur. Unlike all the other comments saying you should just use flatpak
Pacstall is for Ubuntu. I am not sure it can work well for Debian. Yes, sure, it is possible that some Ubuntu users see value in having AUR alike repositories to install from. Actually PPA for Ubuntu (PPA does not work well on Debian I’ve read) is kind of like AUR. The Personal Package Archives are uploaded by someone and provide newer versions of software, or provides software which is not in the main Ubuntu repositories. A good example of that is the PHP packages from Sury : https://deb.sury.org/
