Occassionally it may be desirable to install a kernel+modules package of a forthcoming Linux release, to test or establish some functionality. This is really not for the Newbie as you can mess up your System if the following steps are not followed exactly Lines below beginning with # are my comments. These steps assume an Internet access under LInux. Later I'll describe the alternate case of download under Microsoft $ ls /etc/apt/sources.list /etc/apt/sources.list # is the file with Ubuntu repository information. Make a backup copy for safety. My current system is Ubuntu karmic and the next release will be "lucid". So: $ cd /etc/apt/ $ sudo cp sources.list sources.list.karmic $ sudo cp sources.list sources.list.lucid the latter to be edited $ sudo gedit sources.list.lucid # will show near the top a line: deb http://us.archive.ubuntu.com/ubuntu/ karmic main restricted # the URL stem http://us.archive.ubuntu.com will in general be different in different countries. Keep your own. # duplicate this line and in the 2nd change "karmic" to "lucid" so the line pair reads like: deb http://us.archive.ubuntu.com/ubuntu/ karmic main restricted deb http://us.archive.ubuntu.com/ubuntu/ lucid main restricted # SAVE this edit Get ready for an update including the "lucid main restricted" with: $ sudo cp sources.list.lucid sources.list Update the package lists with: $ sudo apt-get update Search for available 2.6.32 kernels with: $ apt-cache search linux-image | grep 2.6.32 linux-image-2.6.32-10-386 - Linux kernel image for version 2.6.32 on i386 linux-image-2.6.32-10-generic - Linux kernel image for version 2.6.32 on x86/x86_64 linux-image-2.6.32-10-generic-pae - Linux kernel image for version 2.6.32 on x86 linux-image-2.6.32-10-virtual - Linux kernel image for version 2.6.32 on x86/x86_64 linux-image-2.6.32-11-386 - Linux kernel image for version 2.6.32 on i386 linux-image-2.6.32-11-generic - Linux kernel image for version 2.6.32 on x86/x86_64 linux-image-2.6.32-11-generic-pae - Linux kernel image for version 2.6.32 on x86 linux-image-2.6.32-11-virtual - Linux kernel image for version 2.6.32 on x86/x86_64 linux-image-2.6.32-301-ec2 - Linux kernel image for version 2.6.32 on x86/x86_64 linux-image-2.6.32-9-generic - Linux kernel image for version 2.6.32 on x86/x86_64 For my System, the appropriate kernel package is the 2.6.32-11-generic choice. To get this and the linux-headers needed for compiling: $ sudo apt-get install linux-image-2.6.32-11-generic linux-headers-2.6.32-11-generic which will also install a linux-headers-2.6.32-11 dependent for linux-headers-2.6.32-11-generic Once this install is done, IMMEDIATELY restore to the pure karmic package lists, because if an automated upgrade runs, it will start a download of ABUNDANT lucid packages and most likely break your karmic system. SO DO: $ sudo cp sources.list.karmic sources.list and again do: $ sudo apt-get update during which the "lucid main restricted" package list will be eliminated. Next reboot using the 2.6.32-11 choice. I have done so without harm on my otherwise Karmic system. Should the boot fail, just poweoff and choose the karmic kernel on your next boot. Fortunately the forthcoming lucid release is still using gcc-4.4, so modem drivers compiled for 2.6.32-11 will be compatible. Should there have been an upgrade to gcc-4.5, one would also have had to: $ sudo apt-get install gcc-4.5 and deal with choices between gcc-4.4 and 4.5 when compiling. Ibrahim has the DKMS module update system installed, so his needed agrsm drivers will be compiled and auto installed during these processes. If one does not have Internet access under Linux yet, just bypass all the above. Go to: http://packages.ubuntu.com/ and search for each of: linux-image-2.6.32-11-generic linux-headers-2.6.32-11-generic linux-headers-2.6.32-11-generic After manual download and coping to your Linux partition, they can be coinstalled with: $ sudo dpkg linux*.deb MarvS
