I'm not a software dev, but I'm curious why Calibre for Linux doesn't use an Appimage or Flatpak release. I read the Linux install notes on
https://calibre-ebook.com/download_linux, and the question occurred to me. If Calibre is going to use custom copies of its needed dependencies, why not use one of those packaging formats? It seems like the app would be easier for users to update that way. Besides that the only reason I see people dis those packaging formats is that they require the extra space for all their necessary dependencies to run. So if we're going to have the extra footprint, why not have easy updates? Idk.
I am not claiming this is what should be done btw. I'm not a dev, and I don't think I somehow know better. I only switched to Linux in 2024, so please educate me if I'm missing something.
