Packaging Qt applications on Linux
Things are more complicated on Linux than on Windows. There are two popular package formats: RPM Package Manager (RPM) and Debian Binary Package (DEB). RPM was originally developed for Red Hat Linux and it's the baseline package format of Linux Standard Base. It's mainly used on Fedora, OpenSUSE, Red Hat Enterprise Linux, and its derivatives; while the latter is famous for being used in Debian and its well-known and popular derivative, Ubuntu.
In addition to these formats, there are other Linux distributions using different package formats, such as Arch Linux and Gentoo. It will take extra time to package your applications for different Linux distributions.
However, it won't be too time consuming, especially for open-source applications. If your application is open source, you can refer to the documentation to write a formatted script to compile and package your application.
