[debian] install failure, fso-frameworkd is not going to be installed

[Neil Jerram]

Just reinstalling debian, and the fso stage fails with:

root at om-gta02:~# ./install.sh fso
Running stage fso
Installing FSO-specific packages
Reading package lists... Done
Building dependency tree
Reading state information... Done
pkg-fso-keyring is already the newest version.
Package xserver-xorg-input-all is not installed, so not removed
[... repeat for lots of other xserver-xorg-input-* packages ...]
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  zhone-session: Depends: fso-frameworkd but it is not going to be installed
E: Broken packages

(I originally ran ./install.sh all, and that failed in exactly the
same way.  I then ran ./install.sh fso, to be sure, and to get the
exact output to copy here.)

Any solution?

Thanks,
