If you’ve ever encountered the error message “Grub 2 install error: /usr/lib/grub/i386-pc/modinfo.sh doesn’t exist” while trying to install or update GRUB on your Linux system, you know how frustrating it can be. This error typically occurs when the system cannot find the necessary GRUB files in the specified directory.
In this article, we will provide step-by-step solutions to fix this error.
Understanding the Error
Before we dive into the solutions, it’s important to understand what this error means. GRUB, or the Grand Unified Bootloader, is a program that allows your computer to boot into its operating system. When you see the error message “/usr/lib/grub/i386-pc/modinfo.sh doesn’t exist”, it means that the system is unable to locate the necessary GRUB files to boot up your system.
Prerequisites
Before we begin, you need to have a live CD or USB of your Linux distribution. This is crucial because we will need to boot from this live session to fix the GRUB error.
Solution 1: Installing the grub-pc package
Step 1: Booting from the live CD/USB
First, boot your system from the live CD/USB. Once you’re in the live session, open a terminal.
Step 2: Mounting the necessary partitions
In the terminal, run the following commands to mount the necessary partitions:
sudo mount /dev/sda1 /mnt
sudo mount /dev/sda1 /mnt/boot
sudo mount --bind /dev /mnt/devHere, /dev/sda1 is the partition where your system is installed. This might be different on your system, so adjust accordingly.
Step 3: Changing the root directory
Next, change the root directory by running the following command:
sudo chroot /mntThis command changes the root directory to /mnt, which is where we’ve mounted our system partition.
Step 4: Installing the grub-pc package
Now, install the grub-pc package by running:
sudo apt-get install grub-pcThis command installs the grub-pc package, which should resolve the error.
Step 5: Installing GRUB
Finally, install GRUB by running:
sudo grub-install /dev/sdaThis command installs GRUB on your system.
Solution 2: Installing the grub-pc-bin package
If the first solution doesn’t work, you can try installing the grub-pc-bin package instead of grub-pc. Follow the same steps as in Solution 1, but in Step 4, run:
sudo apt-get install grub-pc-binPlease be cautious as installing grub-pc-bin may remove grub-efi-amd64 and potentially cause issues.
Solution 3: Installing the grub-efi package
If neither of the above solutions work, you can try installing the grub-efi package. Follow the same steps as in Solution 1, but in Step 4, run:
sudo apt-get install grub-efiAfter the installation, proceed with the GRUB installation as before.
Conclusion
In this article, we’ve provided detailed solutions to fix the “Grub 2 install error: /usr/lib/grub/i386-pc/modinfo.sh doesn’t exist” error. By following these steps, you should be able to resolve the issue and successfully install GRUB on your system. If you continue to experience issues, please provide more information about your system and any other error messages you encounter.
GRUB, or the Grand Unified Bootloader, is a program that allows your computer to boot into its operating system. It is responsible for loading the kernel and initiating the boot process.
This error message typically occurs when the system cannot find the necessary GRUB files in the specified directory. It may be due to a misconfiguration or missing packages.
To fix this error, you need to have a live CD or USB of your Linux distribution. This is necessary to boot from the live session and access the necessary tools to fix the GRUB error.
Solution 1 involves installing the grub-pc package. It includes steps such as booting from the live CD/USB, mounting the necessary partitions, changing the root directory, installing the grub-pc package, and finally installing GRUB.
Solution 2 is an alternative to Solution 1. If Solution 1 doesn’t work, you can try installing the grub-pc-bin package instead of grub-pc. The steps are the same as in Solution 1, except for the package installation step.
Solution 3 is another alternative if neither Solution 1 nor Solution 2 work. It involves installing the grub-efi package instead of grub-pc. The steps are the same as in Solution 1, except for the package installation step.
If none of the solutions work, it’s recommended to seek further assistance. Provide more information about your system, any other error messages you encounter, and seek help from the Linux community or a professional for troubleshooting.
