qemu-system has unmet dependencies

[acerv]

When trying to build the docker with command:
sudo docker build -t lavadev .

I have the following error:

The following packages have unmet dependencies:
qemu-system : Depends: qemu-system-sparc but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

QEMU 2.7 has been backported to jessie-backports, and has a broken dependency. It needs a newer openbios-sparc package.

Until it's fixed in jessie-backports, you can replace qemu-system in Dockerfile:
qemu-system \
by
qemu-system-arm qemu-system-mips qemu-system-ppc qemu-system-x86 qemu-system-misc \

We filter out qemu-system-sparc from the list to install.

With more thoughts, we can probably get rid of qemu-system and only install the architecture that are really supported by LAVA like qemu-system-arm and qemu-system-x86.

The bugfix works, but now I have an another problem with python dependences:

dpkg-checkbuilddeps: Unmet build dependencies: python-sphinx (>= 1.4)

[fboudra]

right. You need python-sphinx from jessie-backports too now.
