changes that made 8.04 upgrade work using aptitude

[chuck adams]

This is where I did something and I want to understand
what it is that I did.

I was doing the suggested 

sudo aptitude update
sudo aptitude safe-upgrade
sudo aptitude full-upgrade


Previously I ran into the corrupted tarfile messages
for things that seemed to be broke.  

Today I closely looked at the error messages and
they all pointed to   /var/cache/apt/archives/
where the deb files were cached.

So I did a 

sudo rm -f /var/cache/apt/archives/* /var/cache/apt/archives/partial/*

then when I redid the above sudo aptitude  sequence everything
was correctly installed, including the new kernel and nvidia-glx-new.

I did a reboot and the new kernel came up.  But, like everyone
else in the universe it seems that my sound broke and the speaker
icon now has a red X across it.

xorg.conf in /etc/X11 was not modified, so I'm going to experiment
with bringing across a xorg.conf from another working system and
see if the nvidia video card works at the higher resolution.

The thing that I am not understanding is the   rm   of the archives.
I would have thought that a   sudo aptitude clean   would have
done something to remove the old files to make room for or force
a new download.   My ignorance and/or stupidity at work.

FYI and thanks for any help forthcoming,

Chuck
