Comparative Analysis of Universal Methods for Package Installation in Linux

Here, I have shown 4 different universal methods of installing an app package in Linux. The following comparison of all four methods will help you get an easier understanding of which method is more suitable for your usage:

Methods	Pros	Cons
PackageKit	User-friendly and visually easier to use.	Not all app packages are in the default repository of the Ubuntu Software app.
Snap	Cross-distribution support. Isolated environment.	Separate package management system.
Flatpak	Cross-distribution support. Independent of system library. Isolated environment.	Larger file size. Longer setup & startup time.
AppImage	No installation is needed. Cross-distribution support. Portable.	No automatic update. The latest version of the app may not be available.

If you prefer the command line interface then you can use any method except the 1st method, if you prefer GUI then use the 1st method.

Error While Opening AppImage

When you are trying to open the AppImage file in your system you may see an error like dlopen ( ): error loading libfuse.so.2 that means libfuse.so.2 library is missing on your system or there are some issues with this version:

The AppImage file usually doesn’t require any special tool to run but some AppImage requires a utility named Fuse to run properly. To solve this problem you can simply install the fuse package in your system before opening your AppImage file. You can execute the following command in the terminal to install the fuse app package:
