A.1. Upgrading your etch system
A.2. Checking your sources list

This appendix contains information on how to make sure you can install or upgrade etch packages before you upgrade to lenny. This should only be necessary in specific situations.

A.1. Upgrading your etch system

Basically this is no different than any other upgrade of etch you've been doing. The only difference is that you first need to make sure your package list still contains references to etch as explained in Section A.2, “Checking your sources list”.

If you upgrade your system using a Debian mirror, it will automatically be upgraded to the latest etch point release.

A.2. Checking your sources list

If any of the lines in your /etc/apt/sources.list refer to 'stable', you are effectively already “using” lenny. If you have already run apt-get update, you can still get back without problems following the procedure below.

If you have also already installed packages from lenny, there probably is not much point in installing packages from etch anymore. In that case you will have to decide for yourself whether you want to continue or not. It is possible to downgrade packages, but that is not covered here.

Open the file /etc/apt/sources.list with your favorite editor (as root) and check all lines beginning with deb http: or deb ftp: for a reference to “stable”. If you find any, change stable to etch.

If you have any lines starting with deb file:, you will have to check for yourself if the location they refer to contains an etch or a lenny archive.


Do not change any lines that begin with deb cdrom:. Doing so would invalidate the line and you would have to run apt-cdrom again. Do not be alarmed if a 'cdrom' source line refers to “unstable”. Although confusing, this is normal.

If you've made any changes, save the file and execute

# apt-get update

to refresh the package list.
