Upgrade Debian: Etch to Lenny

Add new public key

gpg --keyserver wwwkeys.eu.pgp.net --recv-keys  9AA38DCD55BE302B
gpg --armor --export 9AA38DCD55BE302B | sudo apt-key add -

Update packages

1) Edit /etc/apt/sources.list and replace "etch" to "lenny"

2) Do the upgrade

aptitude update
aptitude install dpkg aptitude apt
aptitude full-upgrade

Configuration files:

• Except special configurations overwrite /etc/securetty

Problems generated by the upgrade:

• salsauth not staring because now require run directory
• courier-imap-ssl does not work with fetchmail because of SSL version issue
• MoinMoin stop working (http error 500)
• Trac stop working
• Mailman switch default language english
• Xen kernel not upgraded / Hypervisor not upgraded too
• udev

Notes for Xen users

My way:

DomUs

1. Upgrade all DomUs
2. Install kernel modules
3. Install udev
4. Shutdown all DomUs

Dom0

1. Upgrade Dom0
   1. Install xen kernel and hypervisor
   2. Change kernel and initrd for all DomUs
2. Reboot
