Debian Lenny stable version is finally released and many are curious to upgrade Debian Etch to Debian Lenny. Debian Etch to Debian Lenny Upgrade is not a difficult task, you can easily initiate the live upgrade with bunch of commands. But before you start the upgrade make sure to take the backup of your important stuffs like web files, database, conf …..Etc.
To Upgrade Debian Etch to Debian Lenny, just follow these 5 steps:
1. First you need to edit the /etc/apt/Sources.list file.
sudo vi /etc/apt/sources.list
sudo nano /etc/apt/sources.list
You may noticed as follow in the Sources.list
deb http://ftp.us.debian.org/debian/ stable main
deb-src http://ftp.us.debian.org/debian/ stable main
deb http://security.debian.org/ stable/updates main
deb http://ftp.debian.org/debian/ etch main
