How do I upgrade from Debian Etch to Debian Lenny?

Hi Folks,

Lenny is out for a few days now and the upgrade process is quite straight forward:
(please do that in textmode and not in your GUI, so KDE or whatever can be restarted without any issues)

  • vi /etc/apt/sources.list
    (change etch to lenny)
    Should look a bit like this:
    deb lenny main contrib non-free
    deb lenny/updates main contrib
  • aptitude update
  • aptitude install apt dpkg aptitude
    (accept the first solution, it is fine)
  • aptitude full-upgrade
    (read through the suggestion, but the first one is usually the best)
  • aptitude upgrade
