Error during upgrade from Lenny to Squeeze
 

Hi,

I followed the official guide in order to upgrade from Lenny to Squeeze.
After reboot, I should execute "apt-get dist-upgrade".
I've done this with "-s" switch (simulate) and I got this error:

how can I solve this?
Thankyou

Judging from this, it seems to be a common issue when dist-upgrading from Lenny to Squeeze using the -s switch. According to the link, this particular error should go away when you actually perform the dist-upgrade (without the -s switch).
