Upgrade kernel to next level (debian 4.0)

[bullz]

Hello Gurus,

I am completely plain here. I tried my best to understand the issue.

OS:- debian 4.0 (2.6.18-4-amd64)

File systems are in read-only ( Below errors are keep throwing an alert on console, every 5 sec ) and I am unable to write any files in / partition.
As per the VM ware KB site, this may be a Linux kernel bug .

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=51306

And the recommendation is to update the kernel to Debian 4.0 r9

1) r9 what indicates here?
2) What is the current version of the kernel (2.6.18-4-amd64)
3) If that’s the case, how can I upgrade the kernel to r9 from an existing version

Hi bullz,

Check the following link -
http://ftp.debian.org/debian/
-> Look for "Debian 4.0r9"
This has documentation for "Installation and Upgradation".

Hope this helps.

Hi bullz,

>> r9 what indicates here?
Lets look at the version - 4.0.r9
here,
* 4.0
The Version 4.0 corresponds to a stable release.

* r9
The version r9 corresponds to a 9th point release.
Stable release gets minot updates (point release) until the next stable release.
All the bug fixes after Version 4.0 would go in to the point releases.
The point release gets metnioned after the main release along with the the
letter r.

>> And the recommendation is to update the kernel to Debian 4.0 r9
Looks like the problem you are facing is a known problem and is already fixed.
This fix is present in the point release 4.0 r9.

You are currently at a major release of 4.0. In order to get the fix, you need to
upgrade from the current major version 4.0 to point release of 4.0.r9.

You can use the link in my previous response for the upgrade instructions.

Good luck with the upgrade.

Debian 4.0 is oldstable, it no longer receives security updates. The current, stable version is 5.0

The kernel in 4.0r9 is 2.6.24. Updating the system is usually done with 'apt-get update' followed by 'apt-get upgrade'.
However, according to http://www.debian.org/News/2010/20100522 this could not be as easy. You will probably have to edit your /etc/sources.list file to point apt/aptitude to the archive mirrors before an upgrade to 4.0r9 could be done.

Thanks folks, for your help.
The doc/link are seems to be very broad, could you please help me to spot the exact topic/procedure/steps of upgrading Debian kernel version from 4.0 to 4.r9?

Hi bullz,

Yes, the current stable version of debain is 5.0 (code name lenny).
You need to upgrade to this version.

For step by step procedure for upgrading fom Debian 4 to 5, refer

-> These links talks only about the upgrade.

Good luck with the installation.

Wonderful â Muralidhar Kiniâ

Thanks for this linksâ ¦.

But, I do want an option of upgrading to 4.0 to 5.0
Here, I want only the upgrade version of 4.0 to 4.r9

I hope, below commands can update/upgrade to the latest upgrade version of the same version.

# apt-get update
# apt-get upgrade

Please correct me if I am wrong.

To add,

Please find the details of the current version.

ii linux-image-2.6-amd64 2.6.18+6 Linux kernel 2.6 image on AMD64
ii linux-image-2.6.18-4-amd64 2.6.18.dfsg.1-12etch2 Linux 2.6.18 image on AMD64
ii linux-image-amd64 2.6.18+6 Linux kernel image on AMD64


I need this to be upgraded to linux-image-2.6.26

Please advise experts

Hi Bullz,

>> Here, I want only the upgrade version of 4.0 to 4.r9
Any particular reason why you want to upgrade only to 4.r9 and not to 5.0 ?

Its always advisable to upgrade to the latest version. If there was some bugs in
4.r9 that are fixed in 5.0 then you would face some more problems in 4.r9.
Instead you can upgrade to the latest version of 5.0, so that you would have
fixes to all the known bugs.

I would advise you to upgrade to the latest version 5.0 unless you have some
strong reason for not upgrading to 5.0.

Yes murali,

Itâ s better to upgrade to the next level of OS (5.0)
But, just for my knowledge, I am trying to understand, how can I upgrade the OS to the next release?
For instance here 4.0 to 4.r9

Wish to give you 10 pts soon :)

Yes, thats right.
This command will install all the latest updates to the current Debian version
(4.0 in your case). If you want to go to the latest point release then the above
step should be enough.

However if you want to upgrade from one stable release to another, Say from
4.0 (etch) to 5.0 (lenny) then you need to follow the entire set of steps
mentioned in the above link.

Hmm. Nice way of making sure you get a fast reply!!

Good stuff Murali/expert.

My final doubt on this.

I would doing this activity via apt-get command, as this is fetching the necessary packages from the links specified in the file /etc/apt/sources.list

1) How can I check the file already exists or not?
2) For example 2.6.24 is the new kernel file, how can I check if this is already exist on the site?
3) My current version is linux-image-2.6-amd64 (2.6.18+6), and likely I wanna upgrade this to a next release 2.6.24?

This already exists on the site, check the following -
http://packages.debian.org/etch/linux-patch-debian-2.6.24

Looks like the following command is what you need -
wget http://kernel-archive.buildserver.net/debian-kernel/pool/main/l/linux-2.6/linux-image-2.6.24-1-686_2.6.24-5~snapshot.10625_i386.deb
