Build a debian package from FreeCAD yourself.
 #!/bin/bash set -e ################################# # NOTE: # This assumes you have a user `builder` and a folder `/home/builder/packages`. # it will clone FreeCAD there and start pbuilder using pdebuild. # For me this works using debian sid. (stretch/buster will probably not work!) # # After the build has finished, it will import the packes into a reprepro # which is setup at /srv/repo
