I'm running bt4-pre-final as a VM using VMware WS 7 RC. My host is Windows 7 64 bit.

Installing BT as a VM went ok as long as I had a good copy of the iso.

What I did was:
sudo apt-get update
sudo apt-get upgrade

It downloaded about 94meg and the update was moving right along when I got this:

Processing triggers for lib6c...
ldconfig deferred processing now taking place
Processing triggers for menu...
Errors were encountered while processing:
postgresql-8.3
postgresql
E: Sub-process /usr/bin/dpkg returned an error code (1)

And it stopped.

Did everything that was downloaded get installed?

Thanks,

Ray
