lzma: Decoder error
cpio: premature end of archive

i am using ubuntu 10.10, is there another command to extract lz files? am i missing a parameter?

    You will see this error if you are :

    1. Using a different distribution other than Ubuntu (for example Mint) OR
    2. you have an old version of Ubuntu (eg: Karmic 9.10) OR
    3. you have a disk error OR
    4. you are trying using a software like Reconstructor

    If you want to customize your initrd, i recommend to use the latest version 11.10 and then customize it.
