Linux

I use one command to upgrade the whole system: paru one one system and yay on the other laptop.

Fedora updates flatpaks automatically, system updates too, but you need to reboot. Which Fedora version do you use?

100% agree with you OP.

I think a script with apt/pacman/dnf etc., flatpak update can do the job as well?

IMO its against the unix vision to extend apt to manage flatpak as well.

I use BAUH as a GUI "update everything in one click" does repos, aur, flatpak, snaps, appimages. Paru is CLI option for repo, aur and flatpak. I dunno if it does snaps never checked.

I use very minimal software and usually don't care about Flatpak

emerge -uDN @world

...and head to bed for me.

No need to overcomplicate things, just write a small shell script or even just an alias. I use this daily:

alias get-rekt="sudo apt update && sudo apt upgrade -y && sudo apt autoremove -y && flatpak update -y && flatpak remove --unused --delete-data -y"

adjust accordingly for Fedora and/or snaps. Obviously doesn't work for appimages or manually compiled stuff which should be a last resort if there's no other sensible way to install stuff.

edit: voyager shat the bed with the code block but you get the point

I'm using MX Linux and don't use any flatpak or snaps, only good old debs

I get 99% of my packages via nix and the other 1% through appimages which I can put anywhere I like on my disk

Yeah, flatpaks are a pain in the ass. So glad that I don't have to use them since switching to Arch.

yeah like other people have rec'd, I just wrote a script for installing/removing/upgrading/searching all the package managers I have. this was used as a tongue in cheek jab and has never truly been a brag.

If you want a single command, consider topgrade. Not sure if it supports Flatpak and Snaps yet, as I do not use those (yet).

Perhaps a small bash script to iterate through all of the package delivery mechanisms' for updating everything?

🎶That's why i don't like and use flatpaks, snaps and appimages 🎶

It's wild what can be done with some clever aliases. Linux is better now than ever before.
