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.

GearLever works better
Does it manage the --no-sandbox option often needed?
I have never used that flag. Does that just enable full system access without the usual layer of sandbox protection?
Yes,and it's the only way to start some apps on Ubuntu
Don't run electron/chromium apps with
--no-sandbox, that is not safe, you are exposing yourself to the internet.Canonical decided on ubuntu 24.04 to disable unpriv namespaces in the name of security, in reality they did it to push snaps since that change breaks appimage and flatpak.
Do what linux mint ended up doing and disable the restriction.
Or better yet just don't use ubuntu, it is just a source nightmares, the uuttils switch even broke one of my appimages...
Okay, well gear lever lets you add command line arguments which get saved in the config so that should work easily. I will say it's odd to me that you say this is needed for a specific OS, let alone often. I have never used that flag and I've been using an Ubuntu variant for ~5 years now. Doesn't mean you're wrong or anything, I'm just surprised because that seems to defeat one of the main purposes of appImages. The whole security/safety model seems to be sidestepped if you use that flag. I tend to only use appImage if it's my only option because flatpaks seem to work better in my experience.
Gearlever doesn't even do delta updates, it downloads the whole appimage with every update, and you often have to manually give it the URL to update the appimage.
It is also a total hack written in python, the dev was even shelling out
archto find the host arch instead of using the built in methods of python...
