Bug#645713: Acknowledgement (fails to upgrade a default GNOME desktop installation from squeeze → sid)

[Manuel Rego Casasnovas <rego@igalia.com>]

Hi,

I've had this problem several times past weekends trying to install 
Wheezy from a fresh Squeeze installation.

The concrete steps to reproduce the problem are:
1) Install Squeeze
2) Change your /etc/apt/sources.list from squeeze to wheezy
3) # apt-get update
4) # apt-get upgrade
5) # apt-get dist-upgrade

However, I've been able to avoid this problem skipping point 4). The 
solution for me was:
1) Install Squeeze
2) Change your /etc/apt/sources.list from squeeze to wheezy
3) # apt-get update
4) # apt-get dist-upgrade

And then everything works like a charm.

I hope this helps.

Bye,
   Rego
