Be aware there is generally considerable risk running unmaintained apps, particularly if unimproved for over 3 years.
For very simple, uncomplicated stuff it might be a minimal risk but the more complex the app the more likely the code cannot be considered secure anymore. Would you risk this with a remote acccess app?
Besides, IIRC when I looked at this app a long time ago, there was some kind of code that could be run on an RPM system, there was no need to convert a DEB. For someone who wants to experiment with this, go look for it… It’s the last version that was released.
