Spyder 6 will get a new installer for all platforms and a standalone application for Linux!
Briefly

Spyder's new installers aim to provide a consistent user experience across all platforms while continuing to offer an isolated runtime environment. They support incremental updates and external plugin management, enhancing functionality compared to the previous standalone installers.
Windows users will have a familiar graphical interface during installation. macOS users will switch to .pkg package installers with guided installation. Linux users will be guided by an interactive shell script for compatibility with various distributions.
