Hello.

We have Debian 4.0 running on one of our computers; a server of sorts.

Accessing that computer, for system updates, etc, is done through
telnet.

Running uname -a, which I understand returns the kernel version, returns
2.4.18-bf2.4 #1 Son Apr 14 09:53:28 CEST 2002 i586 GNU/Linux

In searching on the Internet, I cannot find an easy way, using apt-get,
of updating (or upgrading) the kernel, and it is clearly not
automatically done when running apt-get update followed by
apt-get-upgrade.

The GUI system update/upgrade facility on my workstation (also Debian
4.0), automatically includes kernel updates; the last one done today
(from Synaptic File -> History, "linux-image-2.6.18-6-k7
(2.6.18.dfsg.1-18etch6) to 2.6.18.dfsg.1-22").

How do I get what automatically works with the GUI update/upgrade
facility, to work with a command line apt-get update then apt-get
dist-upgrade facility, to update/upgrade the kernel?

Thank you in anticipation.

Hi Bret,
1. At the console type "aptitude search linux-image" You will see a list of
kernels.
2. Pick the kernel of you choice, say, linux-image-2.6.25-2-686, and AS ROOT
or using sudo type "aptitude install linux-image-2.6.25-2-686" (if that's
the kernel you want).
Then reboot and you should see the newly installed kernel appear on your
boot menu.
Cheers,
Jonathan

But, which image?

The CPU appears to be a Pentium MMX.

The above list of images, have images for 486 CPU's, and for 686 CPU's,
and for "PPro/Celeron/PII/PIII/P4" CPU's, but not for either a straight
Pentium CPU, or for a Pentium MMX CPU.

I am pretty sure 486 is the one to go for. (I use it on a P266 MMX
laptop).

Your list above shows no packages marked 'A' for auto which explains why
it was not upgrading.

Regarding etch, this article might be of interest/use:

It got too complicated, as the process came up with a message about having to modify lilo.conf to accommodate initrd and to modify the file further, to stop the warning message about initrd in future kernel
upgrades.

So, I took the abort option, which still installed some of the 8 new packages to be installed as part of the kernel upgrade process.

I am hoping that the server still works, as it is our mailserver.

I am sure that I will soon find whether the server still works.

Thanks anyway.

It is just to complicated for me at present.

I guess we will just stick with the 2.4 kernel, until upgrading it gets easier, or we replace the computer.
