> Yes my TTY experience is petite at best, and yes there have been three
failed upgrade attempts via update manager. when I click on the details
button I can monitor, to an extent, what is happening, but I don't know how
to save it. I recall something like "unexpected multiple test files"  and a
statement "this may not work well" . I have the functioning 12.04 system on
the 1TB and the 250GB drives. I could experiment using the TTY method
suggested above, but would this give me a way to save/share errors I might
encounter along the way?
