what is the best option to make a live and installable CD of a running ubuntu system –  user279752 May 9 '14 at 12:30

Its happening because there is a deb-src line in your /etc/apt/sources.list file. Either remove or comment this out:-

deb-src http://www.remastersys.com/ubuntu precise main

It's outdated and doesn't work now. –  Pavak Paul Jun 13 '14 at 20:31

You can install Remastersys in Ubuntu 12.04

As root - issue

'sudo su' 

in the terminal window prior to the following command.

wget -O - http://www.remastersys.com/ubuntu/remastersys.gpg.key | apt-key add -

sudo gedit /etc/apt/sources.list

Add the following line

#Remastersys Precise
deb http://www.remastersys.com/ubuntu precise main

Now open the terminal and type

sudo apt-get update && sudo apt-get install remastersys remastersys-gui

Here is the screenshot

Your "as root, issue sudo su" is a bit redundant as sudo brings you to root and the "as root" part assumes the user is already running as root. –  hexafraction Jul 19 '12 at 19:54

Two things - one; I believe they've started up work on Remastersys again.

Two; Relinux seems nice and has a purpose, but it is NOT the same as Remastersys. When it comes to creating installable live CD clones of a system with its installed software, it fails miserably. With Relinux, you get the base OS, plus whatever packages you include via Relinux. Very nice, to be sure, but a far cry from Remastersys's simple elegance of just grabbing and wrapping up everything exactly as it is for your later live-disc amusement.

Relinux may be "better" at making a particular distro, but FAILS MISERABLY if what you want is a live image of your current system.

-Remastersys is no longer supported, actually-. There is a new project, Relinux, that aims to be better than Remastersys ever was, while allowing you to do the same thing (remaster your system).

See this blog for full details: https://relinuxkit.wordpress.com/

-1 ,Because Remastersys still supported :) –  Tachyons May 25 '12 at 4:25
remastersys was never official, but it generally worked pretty well. So, i suppose it was 'never supported' by ubuntu. It does still seem to work and the dev seems to want to sort out people who think its dead. Inaccurate as such, but i'll let it pass cause i've learnt of a new tool ;p –  Journeyman Geek Jun 26 '12 at 5:09

On 140214 Fragadelic posted in the Forums that Remastersys for 12.04 and 12.10 would remain at the repo for another year.

I tried several automated packages for last week trying to make a custom distro. The only one I could run/install were remastersys and relinux. Remastersys is a mess. 2 days I am fighting with relinux, as base system Lubuntu 13.10 32 bits/ 64 bits. I generated the ISO several times and I cannot pass:

  1. The generated ISO wont play on virtual box whatsoever.
  2. The life option of the ISO burned on DVD hangs forever in different places.
  3. The install OS option of the ISO blanks the screen and does nothing after some console outputs.

Sorry to drudge this up again, but we are planning on forking remastersys. For now we haven't made any changes, but we are preparing to keep it going. We are going to change the name. I just installed it from this source on xubuntu 14.04:


It did have a dependency of plymouth-x11.

so download:


sudo apt-get install plymouth-x11       
sudo dpkg -i remastersys-gui_3.0.4-1_amd64.deb  

If you don't see it in your menu, you can start it from a terminal by running this command

sudo remastersys-gui 

Keep in mind this is all stock we have not made any changes to it yet, but I have tested this and it works on my Xubuntu 14.04 laptop

We will be changing the name soon, and will try and get it back into the main repos.

I've managed to install remastersys on a Minimal Ubuntu i386 32 bits.

1. Adding remastersys repository as Eliah and Tachyons posted:

You can install Remastersys in Ubuntu 12.04

As root - issue

sudo su

in the terminal window prior to the following command.

wget -O - http://www.remastersys.com/ubuntu/remastersys.gpg.key | apt-key add -

sudo gedit /etc/apt/sources.list

Add the following line

#Remastersys Precise deb http://www.remastersys.com/ubuntu precise main

2. Installing remastersys and its dependencies :

sudo apt-get update && sudo apt-get install kpartx-boot kpartx kpartx cryptsetup cryptsetup-bin dmraid libdmraid1.0.0.rc16 kpartx-boot ecryptfs-utils libecryptfs0 libnss3-1d lvm2 libdevmapper-event1.02.1 watershed ubuntu-drivers-common python3-xkit bogl-bterm ncurses-term samba-common keyutils libvte-common libparted-fs-resize0 ubiquity-artwork-2.20.0 ubiquity-casper rdate ecryptfs-utils cryptsetup python3-icu python3-pam archdetect-deb dpkg-repack apt-clone dmraid btrfs-tools ubuntu-drivers-common lvm2 localechooser-data cifs-utils libvte9 mtools syslinux-common ubiquity bogl-bterm memtest86+ casper libdebian-installer4 ubiquity-frontend-debconf user-setup syslinux xresprobe squashfs-tools remastersys remastersys-gui

Thanks to all you people who have been working within these projects!

UPDATE 05.01.2015

The link I provide in this and other instructions in step 2 does not work anymore. However, I had downloaded the Remastersys files before the website shut down and they can be installed perfectly through Ubuntu Software Center. !! I am not sure if the files are available in Ubuntu Software Center, but if you have them on your computer, they can be installed through it.

This set of instructions helped me install and run successfully remastersys on Ubuntu 14.04.1 32bit and also successfully create and use a bootable flash drive with the custom iso I made.

A note: flash drive works unless you manually made an upgrade of the kernel for some reason before.

  1. Press Ctrl-Alt-T and run

sudo apt-get install plymouth-x11

  1. Go to this link and download remastersys version for 32bit or 64bit system


IMPORTANT: I downloaded version 3.0.4-1 i386 and it WORKS I checked 3.0.2- version and it doesn't work.

  1. Open Programs and Updates (search in Dash or in the System's parametres)

  2. In Programs and Updates, go to Other tab and press Add...

  3. Copy/paste this

deb http://www.remastersys.com/ubuntu precise main

and press OK

  1. Now look for two lines with "www.remastersys.com/" in the list you can find on the Other tab and make sure you check both boxes. Enter a password if you are asked to.

  2. Press Ctrl-Alt-T and run

sudo -i

apt-get install remastersys-gui

  1. To open remastersys-gui, you always need root priveleges. So do it in the terminal (Ctrl-Alt-T)

sudo -i
