Ubuntu upgrade 11.10 to 12

WARNING: this version of the GNU libc requires kernel version

2.6.24 or later. Please upgrade your kernel before installing

glibc.

 

The installation of a 2.6 kernel _could_ ask you to install a new libc

first, this is NOT a bug, and should *NOT* be reported. In that case,

please add lenny sources to your /etc/apt/sources.list and run:

  apt-get install -t lenny linux-image-2.6

Then reboot into this new kernel, and proceed with your upgrade
