I’m a FreeCAD developer trying to get in touch with someone who can help us with the ownership of the FreeCAD snap (http://snapcraft.io/freecad). This was created by the community member vejmarie a few years ago, but he’s been missing from the forums for over a year and we haven’t been able to get in contact with him.
The version in the Snap store is based on a 0.17 beta from 2016, but the actual release of 0.17 was done at the beginning of April this year, so the version being offered is significantly out of date. Therefore it would be really great if we could get this ownership situation resolved somehow. If it helps, this is the Launchpad group we use to manage our PPAs: https://launchpad.net/~freecad-maintainers
