package samba4 4.0.0~alpha18.dfsg1-4ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 126

[RobinB]

The system said there was a problem and that I should report it. Further than that I don't know.

I am using Ubuntu 12.04
I hadn't expected anything to happen. I currently get a fair number of error messages, telling me that one or other package that I've installed was unable to install - yet the package installs and works fine.

I am finding that my 12.04 experience is so far extremely resource hungry, with my notebook often grinding to a halt and making me wait for things to happen, which was previously almost unheard of unless I was doing something complex on a huge graphics file.
