i was trying this tutorial(https://help.ubuntu.com/community/EOLUpgrades#SpecificOlder) to upgrade Ubuntu 10.04, but always failed. source.list
deb http://old-releases.ubuntu.com/ubuntu/ lucid main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ lucid-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ lucid-security main restricted universe multiverse
i execute the command : sudo do-release-upgrade -d
the last display on terminal is :
Restoring original system state

During upgrading, there are some error when loading Failed Read Mirror File
and error
