    2. I found that Ubuntu 12.04.5 work with Remastersys. I made a live dvd backup.

    3. I am also trying to Install Remastersys on Ubuntu 12 but its not working so can you please tell me that How you did the installation

  4. I having an issue, the ISO file weighs only 34Ko, yet the entire process seems to be working properly. Do you have an idea of what am I doing wrong ?

    1. Pls check enough space in your hard disk.

    2. I checked the log file, and "isolinux/isolinux.bin" was missing. I had to reinstall syslinux, syslinux-utils, isolinux packages to make it works.
