Following error messages were encountered while installing vim

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!

So a clean sources.list file is needed.

You appear to have a missing vif-script, or network-script, in the
Xen configuration file /etc/xen/xend-config.sxp
Please fix this and restart Xend, or your guests will not be able
to use any networking!
