I assumed the space between -- and reinstall was a typo.

I got as far as here with every command giving errors. One thing I'm not
clear about is when apt-get finishes by saying "E:..whatever.." has it
actually done anything? The man page says nothing about the output.

I got confused here about how many of "these steps" I'm supposed to
repeat and which step or steps are "f" (there are three steps labelled f)
Marius has posted another procedure that seems to me that it might have
a chance of isolating what is causing the problem. So I'm going to try
that rather than repeat these steps.
