"Authentication failure" error message at boot up

[jkarurosu]

I've created a distributable livecd/dvd of my system using the following commands:

1.- respins dist cdfs
2.- respins dist iso custom.iso.

once I boot up using a pxe server I got the error message "Authentication failure" is there any way to remove the authentication and boot directly to the console of the system?

@jkarurosu - Am I understanding correctly that it didn't boot up passed the pxe boot into the grub menu? I am not aware of any authentication added to the iso during the respin process and I don't believe this has ever been tested or confirmed to work via pxe boot. Can you please paste the output of 'cat /etc/*release' on the host system you are trying to respin?

Hi chamuco,

Below is the output for the command 'cat /etc/*release'; also I want to comment that I've just tried to generate the image again using the steps 1 and 2 from my first comment, but this time I mount the image without pxe boot but anyway after the boot I got an error message "(initramfs) Unable to find a medium containing a live file system", attached is a file with the screenshots for the process I'm following.

@jkarurosu - Can you please Uninstall and reinstall from either the Deb package in the Ubuntu directory or from the ppa? I updated the code to fix some issues
