lenny auto upgrade

[Filipe Freire <freirefil@gmail.com>]

Hi,

I am running lenny, kernel 2.6.26-2, on a desktop.  Yesterday I did a update of new packages and many things do not work afterwards. I started with an installation of new packages (as I often do with new updates).  As things were not working well afterwards I run aptitude dist-upgrade.  At the end I lost the network connection.

Lost internet connection, mounting usb, etc.  The usb has been fixed by providing the UUID of the device instead of the name but I still can not get my network connection to work.

My packages are now a mixture of lenny and squeeze.  I was not aware of the new squeeze release.  I locked at possible solutions to get the networking running but nothing works, including the different squeeze intructions in /etc/network/interfaces but to no avail.

Did anyone had a similar problem?  Suggestions are very welcome. 

Thanks in advance,
Filipe
