Same issue here.
Running Kali 32 bits on a VMWare.
Unable to use Nexpose because it works only for 64 bit OS.

Possible solution: https://forums.kali.org/showthread.php?23394-OpenVas-Solution

The problem seems to be that some OpenVAS packages in the repo require libopenvas7, but there remain two, gsd and openvas-administrator, that still require libopenvas6. The update process removes libopenvas6 in favor of libopenvas7 and removes gsd and openvas-administrator along with it, breaking OpenVAS.

Both gsd and openvas-administrator are obsolete components. The new openvas metapackage conflicts with "gsd" so it should be dropped on upgrade. And it should probably be dropped from the repository alltogether.

openvas-administrator has been merged in openvas-manager and the new openvas-manager conflicts and replaces the old package which should also be dropped on upgrade too.

But I doubt that this has anything to do with the problem reported here. It looks more like some bad database migration when switching from v6 to v7.

Due to the age of the OS (Kali Moto [v1], Kali Safi [v2], Kali Rolling 2016.x), these legacy versions are no longer supported.
