Appimages are an insecure packaging system with very limited use cases. Please use Flatpak instead! - trytomakeyouprivate/dont-use-appimages
Appimages totally suck, because many developers think they were a real packaging format and support them exclusively.
Their use case is tiny, and in 99% of cases Flatpak is just better.
I could not find a single post or article about all the problems they have, so I wrote this.
This is not about shaming open source contributors. But Appimages are obviously broken, pretty badly maintained, while organizations/companies like Balena, Nextcloud etc. don't seem to get that.
TIP: Flatpak have a build-in way for creating USB, check out the "flatpak --help".
But the point is with Appimage all that have to be installed is FUSE, which is expected to be installed on most installs when you go to a friend or work where Linux is used.
