Grub - menu.lst not updating

[Qu4rk]

A while back, I commented out all the old entries in my menu.lst with a "#" so that when I look at the boot screen it doesn't have an infinite list of old kernels to load that I never load. Well, I just noticed that the newest kernel from the update is not running. I'm still running .24 kernel. How do I resolve this issue so that:

1) I'm running the correct kernel from todays update.

2) I prevent this from happening in the future.

Thanks

Which version of Ubuntu are you running? Since you appear to be using legacy grub, there's a program called Startupmanager that makes it easy to configure your menu.lst. https://help.ubuntu.com/community/StartUpManager

In order to answer your question we should see the output of the Boot Info Script as described here:

Sorry to take so long, this is the first opportunity I've had to look.

I think instead of commenting out those entries you should have changed the all shown below to a 1 (That's a "one"):


## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

So try removing the comments you added, changing the "all" to "1", and then running:


sudo update-grub

As oldos2er said you can in the future select how many kernels to display using the Advanced tab in Startup Manager:

https://help.ubuntu.com/community/StartUpManager?action=AttachFile&do=get&target=sum-advanced.png

But I think adding those comments in the "automagic" section breaks the ability for legacy grub to update properly.

[presence1960]

Another cause may be when you installed the new kernel were you presented with an option to choose which version of GRUB menu.lst to use? If you were you should choose "use package maintainer version". If you choose one of the other options the new kernel is not added to menu.lst and may need to be added manually.

[Qu4rk]

This didn't work. I uncommented what I commented, did a grub update & I'm still running .24. And I downloaded startupmanager & it only gives me up to .24 kernel. Any other suggestions?

[presence1960]

Look in Synaptic Package Manager to see if the kernel you think is missing is indeed installed. Look under linux-headers-x.x.xx-xx and linux-image-x.x.xx-xx

If it is indeed installed you will manually need to add the entries for that kernel in menu.lst

Open a terminal and run
gksu gedit /boot/grub/menu.lstAdd the red below and make sure you swap xx for the kernel #. Just make sure the complete kernel # matches what you insert in menu.lst

Click save and close the file. Reboot. You should have the new kernel in GRUB menu. If it is indeed installed properly you will be able to boot to it.

To get rid of all those kernels you don't use go to Synaptic Package Manager and mark for Removal or Complete Removal the older kernels these items:

linux-headers-x.x.xx-xx
linux-image-x.x.xx-xx

Mark for Removal uninstalls the packages but leaves them in cache. mark for complete removal uninstalls the packages and removes them from cache so you would have to download them again if you ever decided to reinstall them. With kernels you will usually not want to reinstall them.

This will clean up your GRUB menu.

This worked! Thanks man!


Look in Synaptic Package Manager to see if the kernel you think is missing is indeed installed. Look under linux-headers-x.x.xx-xx and linux-image-x.x.xx-xx

If it is indeed installed you will manually need to add the entries for that kernel in menu.lst

Open a terminal and run
gksu gedit /boot/grub/menu.lstAdd the red below and make sure you swap xx for the kernel #. Just make sure the complete kernel # matches what you insert in menu.lst
