This is sort of an odd question, but my desktop is a core2duo machine,
which means it is capable of 32 or 64 bit operation. The last time I
rebuilt the machine in 2007, there were still a number of deficiencies
in 64bit Linux. However, some time in the intervening time, my clock
started running fast, gaining, say, 15 minutes per hour, even though
ntp was running. I was advised to install the amd64 kernel. Thus I
wound up with a franken-machine with a 64bit kernel and 32bit
userland. One of the problems with this configuration is that apps
which use the kernel and userland versions get confused. For instance,
I can install the amd64 version of VirtualBox, but it will not start
because it gives me "wrong architecture"...
Well, now 64bit is as stable as 32bit, and I want to upgrade my
machine to 64bit userland. Is there a reliable way to upgrade existing
packages? Or is a complete rebuild ("nuke and pave") the best way? I
know I could probably wget every package on my system with a wget
script and do a "dpkg -i *" but that seems frought with danger. On the
other hand, doing a "nuke and pave" means I would be without the
machine for the duration of the build, plus the post-install
configuration means I have to labor to get things back to the way I
like them.
Is there some middle ground?
thanks,

Hi,
I would recommend on backing up your $HOME folder(~) and any .conf
files you modified and then do a clean install, also you can save
package selections so that you can just install them on a new 64-bit OS
like this:
1. On the old system you do:*
/dpkg --get-selections > ~/my-packages/*
(my-packages being the file that you save selection to)
2. On the new system you do:
/*sudo dpkg --set-selections < my-packages && sudo apt-get dselect-upgrade*/
(don't forget to copy my-packages file :) )
That's what I did on my Ubuntu laptop and worked perfectly, but since
Ubuntu is a derivative of Debian it shouldn't be a problem.
Cheers,
Dejan
