From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[SOLVED] Snaps won't send background notifications (lemmy.ml)

edit: It can't send notifs :( https://lemmy.ml/comment/4138651

Is there a way to fix this? I am using an app called Superproductivity, it's a productivity app where you can schedule tasks and keep track of them. Now, the trouble is, it won't run in the background and it won't send me notifications. This seems to be common for all Snaps I have installed, is there a way to solve this and make it notify me even when it's not open?

Also, it also have an app image, do app images have the capacity to notify when they are not open? I have heard they can't run in the background.

Thank you to everyone who try to help me here :)

Containerized applications are applications run in isolated packages of code

My main point is that a running AppImage isn't isolated, it can access and modify any file that the user has the permission to. So theoretically, an AppImage could read and upload your ssh keys or put rm -rf ~ in your .bashrc.

A Flatpak app on the other hand needs to either declare specific permissions in its manifest if it wants to e.g. access your home directory or use xdg-desktop-portal to ask for a permission at runtime. This can help when running proprietary/untrusted software or if you want to control what a program can do and what not.

A more popular example are Android apps which are executed in a strict sandbox and need to ask for permission if they want to read your images, access your microphone etc.

Note that there were some discussions about adding sandboxing to AppImages: https://github.com/AppImage/AppImageKit/issues/152

So do snaps and flatpacks. And they are still consider containerized / sandboxed. Appimages are the predecessors to snap and flatpack. The only difference is unlike Appimages they got it right for the most part.

Generally speaking the Appimages integrate with KDE better than all the other DE’s. The codes for Appimages are still containerized from the OS in general as defined in my last post.
