The package lacks to install default the default material list. Material is in this case physical plastic wire for 3d printing. To create a material yourself a default template is needed to get the dialog window working. Reproducible: Always Steps to Reproduce: 1. Start Cura 2. choose a material for printing e.g. click in the Material Menu Manage Materials 3. choose "Erstellen" (create in English) Actual Results: In the GUI nothing happens. In the starting terminal you get an error message: "Unable to create a new material by cloning Generic PLA, because it cannot be found for the material diameter for this machine." Expected Results: Get a tab where I can enter material properties by changing the default values to the one's I want. (This is what I believe happens if correct installed. It should be at least possible to enter something at all.) The same package issue happened in Arch Linux and in the URL is the link and a description how to solve it or where to download the missing files. The directory with the file definitions contains Cmake data, so it can easily be added in the ebuild to fetch that too and install. In the end there should be a directory /usr/share/cura/resources/materials containing .xml.fdm_material files which is currently missing.
I'v just put together a set of ebuilds for Cura 3.2.1 and its dependencies. The Cura ebuild pulls in the appropriate fdm_materials tarball and installs it in the appropriate location. You can get it through layman: layman -a salfter You can view it here: https://gitlab.com/salfter/portage/tree/master/media-gfx/cura Porting the 2.6.0 ebuilds to 3.2.1 was pretty straightforward: rename them, update the patchfiles, and require Python 3.5 as a minimum instead of 3.4. The fix that pulls in and installs fdm_materials would easily be backported to 2.6.0, if for some reason you don't want to run the current version (3.3 is already in beta).
Fixed with cura-3.3
