Cura is growing more and more dependencies. Since these are often not packaged by the Debian/Ubuntu folks, it would additional packaging for which I don’t have (simply) the time. Furthermore, the benefit of the investment of time is minimal since only Ubuntu users profit in first hand from PPAs. Therefore I decided to put my efforts into flatpaks. The advantage is pretty obvious: one software base to build software on and targetting multiple distributions, e.g. incl. ChromeOS.
There are some software components missing still.
But, however, slicing works so far.
There will be likely a lot that needs to be discussed with Ultimaker to get my patches accepted, therefore, don’t expect fast results.
