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.

Are you using Flatpaks?
Are you trusting Flathub?
Do you bother about the sandboxing and security?

YES. I don't understand this delusion people keep perpetuating. Flatpak has a MILD form of container sandboxing. For a real security sandbox we have Firejails or Bubble wrap.

Flatpak is, at it's core, a software development and distribution packaging format. NOT a security implementation.

I always check my flatpak settings post install before running the app and adjust permissions according to need. I mean it does offer more security to me since it's user installed, I can granularly update permissions and control more or less where and what is can touch.

Alternatives to this are SELinux,AppArmour and firejails which are slightly more inconvenient to use.

To me that is mostly secure,or secure enough.

Well and then there's some immutable distros which might help overall.

If we admit that then an app store where anyone can create an account and upload software becomes extremely problematic. This is especially true wherein clients autoupgrade very quickly.

Step one. Legit package a popular app Step two. Wait for substantial uptake Step three. Mix in some ad or malware and watch a tens of thousands get instantly owned.

Anybody can become a community packager for Debian, Fedora, etc.

[–] [email protected] 1 points 10 months ago (1 children)

Anyone can't become a packager in 30 seconds in an automated process that they can' t repeat the 47th time they transmit malware.

The process is identical.

You show up with a package. It gets a basic review. You are granted commit access to your package. You can push changes.

There is slightly more oversight in that another mentor often also has commit access but they can’t and don’t review everything.
