Refracta Snapshot version 9.0.0 is a Bash rewrite of older versions. If you install from the .deb files, it will replace refractasnapshot_8.x.

To install the gui version, you need both refractasnapshot_9.0.0_all.deb and refractasnapshot-gui_9.0.0_all.deb. 

Then run `refractasnapshot` for the CLI version or `refractasnapshot-gui` for the GUI version.
