Unable to find or install grub on course installation

AnthonyHarrison

Hi! I'm enjoying the course!

In the setup section, I found that some files were not installed, and of those I have failed to install grub.

I''m stuck trying to install it on the message:

E: Package 'grub' has no installation candidate

I am on a MacBook Pro, with VirtualBox, and the latest Ubuntu LTS (minimal installation).

I looked around on the web and tried:

sudo apt-get update; sudo apt-get install --reinstall grub

Package grub is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  grub2-common:i386 grub-pc:i386 grub-efi-ia32:i386 grub-efi-amd64:i386 grub2-common grub-pc grub-efi-ia32 grub-efi-amd64

E: Package 'grub' has no installation candidate

Any pointer?

Regards!

the message is telling you that you have the wrong name. The actual package "grub" is in depends on the distribution etc. Notice it says:

However the following packages replace it:
grub2-common:i386 grub-pc:i386 grub-efi-ia32:i386 grub-efi-amd64:i386 grub2-common grub-pc grub-efi-ia32 grub-efi-amd64

I would do "apt-get install grub2-common ". That is probably all you need. I'm surprised it was not installed by default.

Another option is to go to https://training.linuxfoundation.org/cm/prep and download "ready-for.sh". Then run it as in:

./ready-for.sh --install LFD420

LFD420 is a kernel internals course and everything you need to compile and develop kernels should be gotten that way.
