You should take a backup of your Debian Etch system (you can find some suitable tutorials for this in the Backup category), just in case something goes wrong (but the upgrade worked fine for me).
Before we upgrade to Lenny, we install the latest updates for Etch.
The warning is harmless, because having one key to verify the Release file is enough, but just updating your Etch system once more before upgrading to Lenny should make the warning go away (version 20 of the Debian security team issues updates to packages in the stable release in which they've identified problems related to security.
Make sure that your deb etch main deb-src etch main deb etch/updates main contrib deb-src etch/updates main contribdeb lenny main deb-src lenny main deb lenny/updates main contrib deb-src lenny/updates main contrib because their Etch versions are often unable to handle the upgrade to Lenny: aptitude install dpkg aptitude apt Then we do a minimal system upgrade (because a full upgrade might cause some conflicts at this stage): aptitude upgrade --- If this is a desktop system, you should now check if the package is installed: dpkg -l libfam0c102 | grep ^ii If it is, install its Lenny version now: aptitude install libfam0 --- Afterwards, we can start the full distribution upgrade: aptitude full-upgrade (This command is the same as Hi Raymond If you are using VMware to run Lenny I suggest editing your vmx config file of the virtual machine and change scsi0.virtual Dev = "lsilogic" to scsi0.virtual Dev = "buslogic" Reboot and enjoy!
Just upgraded my ispconfig2 old trusty etch server. I don't seem to need to do any post-configuration (kept the customised config files).
More tweaks may be needed, but mail and web services are back online within a half hour!
The other day, one of our subscribers had asked us just that.
Upgrading to a newer version of Debian is actually relatively simple and for the most part, can be done in very short time with just a few quick steps.
After adding Lenny to your for upgrading, you will most likely see a warning about missing key 4D270D06F42584E6.This is because the Release file for Lenny is signed with two keys, one that is available in Etch, and another one that wasn't initially shipped with it.So if you have Debian Linux installed on your PC and are eager to try out Lenny, go grab yourself a Soda and read on.I do not issue any guarantee that this will work for you!Fixes to the released stable distribution often go through an extended testing period before they are accepted into the archive.However, these fixes are available in the dists/lenny-proposed-updates directory of any Debian archive mirror.
