lUbuntu operating system (Lightweight Operating System) is chosen
considering requirements from libraries where libraries have low configuration desktops in their libraries but still wish to initiate their library web sites,
complete library automation as well as wish to create digital libraries.

Please follow proper installation steps to install livecd if you wish
to have dual boot i.e. windows as well as linux installation on your machines.

If you are installing livecd on a machine which is running under proxy
and if you are unable to browse Internet then on every boot you will have to manually set current date and time. To set current date and time manually run the following command on every boot to set systems current date and time.

root@localhost:date -s "09 NOV 2012 03:35:00"

Please change current date and time as above so that machines behind
proxies can run Internet successfully.
