After clicking install, only freecad-common package is isntalled:

dwaff@ayers2:~$ dpkg -l | grep freecad
ii freecad-common 0.18~pre1+dfsg1-5

And of course, FreeCAD can't be run, even though gnome-software lists is as installed.

workaround: apt-get install freecad

installed packages after executing the workaround:
root@ayers2:/home/dwaff# dpkg -l | grep freecad
ii freecad 0.18~pre1+dfsg1-5 all Extensible Open Source CAx program
ii freecad-common 0.18~pre1+dfsg1-5 all Extensible Open Source CAx program - common files
ii freecad-python2 0.18~pre1+dfsg1-5 amd64 Extensible Open Source CAx program - Python 2 binaries
ii freecad-runtime 0.18~pre1+dfsg1-5 all Extensible Open Source CAx program - runtime files
ii libfreecad-python2-0.18 0.18~pre1+dfsg1-5 amd64 Extensible Open Source CAx program - Python 2 library files
[and a lot of dependencies]

No idea how to fix this. Any pointers to relevant docs please? Is it a bug in gnome-software, its configuration files, or a FreeCAD packaging?
