topgrade VS AppImageUpdate

I'm using Topgrade which do everything at once

But when I update PopOS I use topgrade, and I use it daily. It not only updates via Flatpak and apt it also knows about and updates Snaps, Rust, Node.js, brew and Python and all of the other ways I install software.

If you cannot avoid mixing package sources, then maybe topgrade would be useful to you. It leverages all package managers it can find on your system to upgrade all available packages. It works with apt, dnf, zypper, pacman, linuxbrew, nix, pkgsrc, and everything else you can imagine.

I also recommend topgrade

Enter topgrade

Ooh cool I didn't think to include that functionality nice.. (haha btw i'm using this program to upgrade everything (topgrade) maybe i'll include this if i can)

Try with aptitude or [topgrade][(https://github.com/r-darwish/topgrade).

I realize this isn't an answer to your question, but have you heard of Topgrade? It's basically your script but more.

And update everything with topgrade!

There's an updater for appimages https://github.com/AppImageCommunity/AppImageUpdate

AppImages can contain update information (and even support partial updates using zsync), check out https://github.com/AppImage/AppImageUpdate.

https://github.com/AppImage/AppImageUpdate this only works if the application has information regarding where to fetch the update from...

It would be very nice and handy if we could easily update Tutanota Linux desktop app. Luckily, since it is packaged as an AppImage, there's an easy-to-integrate utility available just for that.

It's not centralised, not like Snap with SnapCraft, not even like Flatpak with it's 'not technically but kinda is in practice' Flathub repository. Anyone can make an AppImage, anyone can host an AppImage, anyone can download and run an AppImage, anyone can implement AppImage integration in a distro, and there's even a nice system for automatic updates for AppImage which again is nicely decentralised.

Some have built-in. some not. Btw I considered AppImageUpdate , but it would become re-install a full new app

The fact is that the delta update system via Zsync and appimageupdatetool are real solutions to the problem, but too many developers do not implement it in their AppImage, myself included.

Btw, regarding Flatpak, I've had multiple issues related to mouse cursor, fonts, and local folder access - all related to the sandboxing of apps, all resolvable, but potentially a problem for a non-technical user. I've had much better experiences with AppImages, but I don't know if they have a graphical app store like interface; even the AppImageUpdate idea is still catching on.
