The latest version 5.0 is available through my private flatpak repository now. On the other hand, the PPAs are disabled and are no longer going to be continued.
The installation is pretty straightforward. Just follow the instructions I made for QGroundControl (org.mavlink.qgroundcontrol) already, but install “com.ultimaker.cura” instead.
The package here is going to be optimized and I’ll try to get patches upstreamed soon. This will help get a clean package that is worth to be shared on flathub.
IMPORTANT NOTE: The current package on flathub is neither made nor maintained by my person. I take no responsibility and no support for it. Cross compatibility with this package is not in my scope!
