Hi all,

I recently attempted to upgrade my kernel from 2.4.27 to 2.6.18 on my
Sarge installation. First off, I had to change my sources.list to use
the Etch packages because of a dependency loop involving libc6.

what was the problem? there are 2.6 series kernel in sarge (2.6.8 I
think). You should be able to just do it without messing with Etch
packages. and since you've started... you may need to finish moving up
to Etch.



However, I did the kernel installation w/ "apt-get install kernel-
image-2.6-686" and the installation completed successfully w/ my Grub
configurations updated automatically.

When I restarted the machine and selected the 2.6 kernel, the boot
process proceeded fine (and I could read all the text scrolling by).
But when it came time to display the login prompt (terminal only, it's
a server, so there's no X11) the screen got all garbled. Essentially
all I can see is flickering black and white boxes covering the screen.
However, I can login and reboot the machine - I just can't see what
I'm typing.

Anyone have any suggestions on this one? I tried installing the kernel-
image-2.6-386 on a lark, but I still ran into the same problem. I'm
not passing any special kernel parameters on boot to the 2.4 kernel
either. What am I missing?

I think there is some new console-font stuff happening. You can see it
with a successful post-sarge boot .. the screen flickers while it sets
up the consoles. Have you tried booting single-user mode?

A

No, I haven't tried booting into single user mode yet. That's a good
idea.

As for the error, I was getting this error when trying to upgrade the
kernel:

kernel-image-2.6-386: Depends: linux-image-2.6-486 but it is not going to be installed
libc6-dev: Depends: libc6 (= 2.5-9+b1) but 2.3.6.ds1-13 is to be installed

Then, I get this error when trying to upgrade libc6:

WARNING: POSIX threads library NPTL requires kernel version
2.6.1 or later. If you use a kernel 2.4, please upgrade it
before installing glibc.
dpkg: error processing /var/cache/apt/archives/libc6_2.5-9+b1_i386.deb (--unpack):

Would it be a good idea to change my sources back to Sarge, apt-get
update and then try installing the 2.6 kernel package again?
Essentially, some packages I'd like to install seem to be giving me
libc6 errors, so the whole point of the kernel upgrade was to be able
to upgrade libc6.

Thanks,
Aaron
