I Can't Update To The Most Recent Kernel/Headers
 

Having ubuntu 8.04, when I updated my computer to the latest kernel and headers through Update Manager, an error popped up. The error stated that it wouldn't update at this time. When I tried to download again, the update was gone in Update Manager.

I checked and I don't have the most recent kernel installed. I still have 2.6.24-19. Accrding to http://www.kernel.org/, the most recent one is: 2.6.27. What do I do to fix this?

.

To be honest, I really wouldn't worry about it unless you have some particular reason for updating the kernel? Also, the ubuntu repos just updated to 2.6.24-21 I think, so 2.6.27 is a fair bit away!

Oh yes, do not compile your own kernel in ubuntu, it will break EVERYTHING! you have been warned!

thanks irishbite.

Ubuntu stabilize their kernels when a new release is due. Inrepid (8.10) beta currently runs 2.6.27; should be out (officially) shortly.

Hi, guys! The first time that I attempted to install the most recent kernel/headers for ubuntu, a Defconf window popped up asking me what I wanted to do. It gives me a list of seven options including, 'keep the local version currently installed' and 'install the package maintainer's version'. I closed the window and then a message came up that stated that the kernel/headers won't be updated. What do I do now?

Ubuntu 8.10 will be released on October 30th. That is just two weeks away on Friday. You will have the latest Linux kernel 2.6.27 when you upgrade to Ubuntu 8.10. You will also get the very latest AMD/ATI video drivers at that time.

Probably means you didn't read the message window properly. I suspect that was for updating your grub config. I expect the kernel was installed o.k., but your menu.lst didn't get updated when you closed the dialog. Check your /boot, and manually add an entry if that is the case.

Hi, syg00. Thanks for the reply.

1)You mentioned that I should add an entry to my /boot. What entry should I enter?

2) Also, the next time defconf pops up again, what option do I choose?

.

1) Do an "ls /boot" and note what entries are there; you'll note they come in "sets" for each kernel Ubuntu ship.
Then go edit /boot/grub/menu.lst (as root) and add an entry if you have a more recent kernel in /boot. Simplest to just copy-and-paste a block, and update the version - say 2.6.24-19-generic to 2.6.24-21-generic (3 times). Add it before the current default entry you see when you boot - that way it'll become the new default.

2) Your choice: if you have no changes to menu.lst, accept the maintainers version, and not have to worry about this again. Else keep your own menu.lst, and modify by hand each time.

syg00, thanks for your needed reply. You must forgive me, but I'm a bit new at this, so I'll paste what I got from 'ls /boot' and 'menu.lst'. This way, you can tell me more precisely what I need to do. This will help me learn too!

As you can see, you have a 2.6.24-21 kernel that is not in your menu.lst. From a terminal use "sudo gedit /boot/grub/menu.lst" and update it so it looks like below. See my comments above for why ...

syg00, I did copy and paste your info into my menu.lst, but when I boot up, I see a bunch of lines come up and one line in particular with a red bullet states that "no module for a 'so-so' kernel is found". Also at bootup, I get an option to choose with kernel to bootup in. I get 2 options: the old kernel and the "new" one. And, when I restart my computer, again, I get a list of lines. At this point, I don't know what to do.

Two posts with same problem?
http://www.linuxquestions.org/questi...s-this-676652/

Did you update the menu.lst with those lines I added in (to show you where to add) or did you perhaps (wrongly) completely replace menu.lst with what I posted ???.
If you are seeing the boot messages, implies the bootsplash isn't working.

Might be best to restore your menu.lst - then re-do the edit if you're confident enough.
