Installing latest version of remastersys on Ubuntu 11.10

 Remastersys is a tool that can be used to do 2 things with an existing Debian,  Ubuntu or derivative installation.

1. It can make a full system backup including personal data to a live cd or dvd that you can use anywhere and install.
2. It can make a distributable copy you can share with friends.  This will not have any of your personal user data in it.

I haven't found any specific method to install remastersys properly. Everytime, some works and some don't. So I try different methods in this order and everytime atleast one of them works. Sounds funny but works for me.

Method 1
1. Go to this link  http://www.remastersys.com/ubuntu/remastersys.gpg.key and save this key on your disk.
2. In synaptic, go to Settings/Repositories; select "Authentication" tab and "Import Key File" just downloaded.
3. Still in synaptic, go to "Other Software" tab and click "Add", then enter the apt line and replace oneiric with either lucid, maverick, or natty to match your Ubuntu version:
    deb http://www.remastersys.com/ubuntu oneiric main
4. Leave the repositories tab and "Reload".
5. Search for "remastersys" and select for install.  Edit/Apply Marked Changes.

This might give error some times.

Method 2
1. Type the following key in the terminal to add the key of the repository to the synaptic.
    sudo wget -O - http://www.remastersys.com/ubuntu/remastersys.gpg.key | apt-key add -
2. Add the following line that corresponds to your version of Ubuntu to your /etc/apt/sources.list

#Remastersys Lucid
deb http://www.remastersys.com/ubuntu lucid main

#Remastersys Maverick
deb http://www.remastersys.com/ubuntu maverick main

#Remastersys Natty
deb http://www.remastersys.com/ubuntu natty main

#Remastersys Oneiric
deb http://www.remastersys.com/ubuntu oneiric main
3. Type the following line in the terminal
    sudo apt-get update
4. Now open the synaptic package manager and search for remastersys and install it.

If the above two methods give error. Remove the packages from your sources.list file.

Method 3
1. Go to this link http://www.remastersys.com/repository/ and download the appropriate version of remastersys. For ubuntu, it will be in karmic folder or similar other ubuntu version.
2. Double click on it so that it may open in software center directly. Now click on install.
