Upgrade from lenny to squeeze
Ástþór IP
Debian has released a stable version of Debian 6.0 (squeeze). If you’re running previous version of Debian, you can easily upgrade.
1. Update all packages currently installed to the latest lenny versions
apt-get update
apt-get upgrade
2. Replace all occurrences of lenny with squeeze in the apt sources file (pico /etc/apt/sources.list). Here’s an example of what the file could look like after the change:
deb http://ftp.uk.debian.org/debian/ squeeze main non-free
deb-src http://ftp.uk.debian.org/debian/ squeeze main non-free
deb http://security.debian.org/ squeeze/updates main contrib
deb-src http://security.debian.org/ squeeze/updates main contrib
3. Update apt repository
apt-get update
4. Upgrade apt, dpkg and aptitude packages first
apt-get install apt dpkg aptitude
5. Do a dist-upgrade to upgrade the rest of the system
apt-get dist-upgrade
6. Reboot
reboot
7. Check the debian version
cat /etc/debian_version
It should read version 6.0.0 or greater

Step 4 is done by the system. First the new versions of apt and dpkg are unpacked and configured. Then other packages are installed using the new apt and dpkg.
Why is step 1 needed?

about 1st step : if you regularly do update/upgrade, you do not need it, but it does not hurt to do it once more. some people maybe do not do it often.

You really can need more than step 1. You need the package system in a clean state, if step 1 show errors you need will fix them.

True that installing apt and dpkg first likely isn’t necessary, and in any case will pull half the very dist-upgrade in dependencies. Still this guide helped me a lot to get the idea.
Since I encountered special problems – buggy old motherboard that froze in mid dist-upgrade, plus some inconsistencies in the old system -, I had to resort to more trickery and would like to share what prove useful. “dpkg –configure -a” helps to recover from confuse package situations as good as possible, at least good enough to continue and/or try your last package install or upgrade again; additionally I ran into a full root partition due to apparently a lot of packages provisionally kept stored due to the interruptions and multiple dist-upgrade attempts, “apt-get clean” deleted what was not needed and saved me resizing or manually deleting stuff on a best-guess basis. Be it mentioned that in my situation, it wasn’t before I removed and re-installed the “gnome” package (with aptitude, this time) that I got desktop login and synaptic back, but a) this doesn’t seem the most elegant way and b) the problem will probably not happen when dist-upgrading from a healthy gnome, which I didn’t.
Thanx for the guide, on debian.org upgrading to anything else than stable or newer isn’t covered a lot.
