That error message appears if the daemon service is restarted while the
daemon is not running. It should be fixed. Could you please open a new
ticket in the bugtracker? See instructions given in [1]. Give a clear
description of the problem and the way to reproduce it.

You should have been prompted for the configuration. Did you already
have installed/configured the package before on that system?

Could you please try to reproduce the problem on another system?

See my explanation above :)

According to the logs, you somehow fixed the import gtk problem since
the sand-manager complains about missing encapsulation modules. Did you
remember what you tried between the 'import gtk' problem and the
'missing encapsulation modules' one?

The problem about 'missing encapsulation modules' happens because at
least one encapsulation module is required. You need to install one of
them (ATM/AAL5 for example).

Could you please open another ticket in the bugtracker? See instructions
given in [1]. Give a clear description of the problem and the way to
reproduce it.


To avoid Polish, use LANG=C LC_ALL=C before the commands, eg.:
  $ LANG=C LC_ALL=C dpkg -i some_package.deb

That's strange. You should have the debconf python module. Could you
please send me the result of the following commands:
 $ ls /usr/lib/python*/dist-packages/debconf.py
 $ python --version
 $ sudo python --version
 $ env | grep -i python
 $ sudo env | grep -i python

I re-wrote that part this morning. Did you installed the dependencies
listed by [2]?

I think so. The previous commands will maybe help us to understand the
problem.
