Is this the same machine that you had all the problems with dpkg a few
days ago?  If so I suspect you may somehow have irretrievably damaged
your system so that a re-install is the only way out.

If you do re-install then start keeping careful notes of everything
that you do so that when problems arise you know what it is that you
did to cause the problem.  This often makes it easier to recover from
such situations.
