Ubuntu – How to upgrade the kernel of Xubuntu 15.04 Live CD to latest 4.1/4.0.6 version


I am trying to upgrade the kernel of Xubuntu 15.04 AMD64 live CD to the latest version available (4.1/4.0.6) so that I can try and install the same on hitherto unsupported hardware.

I am using the process outline here.

Here I am installing the Kernel .deb files from Ubuntu Mainline archive in the CHROOT environment and removing the stock kernel using dpkg and apt-get. But all my attempts have been unsuccessful so far.

The boot process fails after loading initramfs with – AuFS: unable to mount root file system.

What am I doing wrong?

I guess you will be happy by having a look at liveng.readthedocs.io and Open Secure-K OS on GitHub.

The full aim of the liveng project is to give the Community a set of best practices in order to turn a common Debian Linux live into a live(ng) operating system which features:

  • native encrypted persistence;
  • kernel update (on a live ISO 9660 filesystem);
  • UEFI, with UEFI Secure Boot compatibility, with a real efi partition.
