how to update GRUB?

[tramir]

What do you want to update? grub itself or the options?

[Prospero2006]

The configuration file is located in
/boot/grub/menu.list

Open in a text editor.

or install kgrubeditor. For all you non-binary people.

I want to upgrade grub itself.

[bumanie]

Try this
sudo apt-get update grub

[sharks]

it says
E: The update command takes no arguments

[bumanie]

Sorry, my mistake, I think it's
sudo update-grub

[sharks]

If a newer version of GRUB is released how do i upgrade it via terminal?

[drs305]

The update-grub command is used to generate and update the menu.lst, according to the man page. The latest grub version in the repos is 0.97-29.

This should upgrade installed packages, including grub:

sudo aptitude update
sudo aptitude upgrade

For updating grub menu items, displays, etc I strongly recommend startupmanager.

You can run the commands from the recovery mode, although when you state 'upgrade grub' that can mean different things. If you select "netroot" (root shell with networking) you will be able to connect to the Internet and run any of the normal update commands such as apt-get update and apt-get upgrade. Since this is a root shell, you do not need to use "sudo".

You can also run the "grub" command or "update-grub" from the root prompt if that is what you are having difficulties with.

I just entered

sudo apt-get upgrade grub
and it worked perfectly fine =)
