Ubuntu 12.04 LTS – Installing Remastersys

O Remastersys allows us to create a custom live cd.

On this CD we will have all the programs that are installed on the computer, so it becomes very useful when installing programs on various computers.

Before you begin install the Synaptic.

Open the terminal 'CTRL + ALT + T', and type:

$ sudo apt-get install synaptic

The following text was based on the address Remastersys, some parts I simply translated. In version 3.0.1-1 for Ubuntu, there is a signed repository that can be added to your system.


Access:Right-click, and save the file to a place where you can find it.

Example: Desktop, / tmp / / home / YOUR USER.


In Synaptic, go to: Settings -> Repositories

Click on the 'Authentication' tab, then 'Import Key File', and locate the downloaded file.


Still in Synaptic, go to the 'Other Software' tab and click 'Add'.

Copy the line below and paste it into this box:

deb http://www.remastersys/ubuntu oneiric main


Close the Repositories window and click 'Reload'.


In the 'Fast Filter' box, or press 'CTRL + F' and type: remastersys, right-click -> Mark for installation.

That done, click on 'Apply'.

If you still can't, then use the Manual Method.

Open the terminal (CTRL + ALT + T), download and apply the repository GPG key.

$ sudo su # wget -O – http://www.remastersys/ubuntu/remastersys.gpg.key | apt-key add –

Adding the repository to the file "/etc/apt/sources.list".

Copy and paste the line below:

# echo "deb http://www.remastersys/ubuntu oneiric main" >> /etc/apt/sources.list

Update the package list:

# apt-get update

If all went well:

# apt-get install remastersys

Accept with 'S' + ENTER.

If all went well, now type in the terminal:

$ remastersys-gtk

Now just customize your distro.

But don't forget to disassemble all mounting devices, this can be done with the command:

# umount -a

Also be sure to list the directories / folders you do not want to include in your LiveCD.

Example: in Files to exclude: / home / YOUR.

Now s enjoy, click on Guide: Actions -> Dist

Wait a few hours to finish building your LiveCD ISO.

This done, note that the ISO stands at: / home / remastersys / remastersys

Another option, if you like me want a graphical interface for your remastersys, install the remastersys-gtk package with the command:

sudo apt-get install remastersys-gtk

and open it from the Ubuntu dash.
