Ubuntu 10.04 Installation problem

[mamadou diop]

Hello, I have installed fai on Ubuntu lucid. During the installation of the
client, after partitioning
the hard disks, it is displayed many times "couldn't find package whose name
or description matched by package_name".
And the system rebooted and displayed "Error while loading the operating
system".
After replacing my FAI server Ubuntu 10.04 by a FAI  server Ubuntu 8.04, the
client is installed successfully.
What's the problem of FAI in Ubuntu lucid?
