LinuxQuestions.org - dpkg error code 1

I was triyng to install Debian on a AMD K6-2. I use debootstrap, and installed Lenny, with a kernel linux-image-2.6.26-2-486.

After that apt-get update and apt-get upgrade and I get:

Since release 150, udev requires that support for the CONFIG_SYSFS_DEPRECATED
feature is disabled in the running kernel.

Please upgrade your kernel before or while upgrading udev.

AT YOUR OWN RISK, you can force the installation of this version of udev
WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM
AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file.
There is always a safer way to upgrade, do not try this unless you
understand what you are doing!
