This article provides a detailed guide on how to troubleshoot and solve the common issue of a Ubuntu 22.04.5 LTS system that fails to boot on a laptop due to a low battery or a failed update. The article covers key concepts related to this issue, including GRUB and boot options, and explains how to resolve the problem step-by-step.
Introduction
Upgrading or updating a Ubuntu system is a routine task. However, sometimes issues can occur during the update process, causing the system to become unbootable. This can be frustrating, especially if the laptop's battery level is low. This article provides a detailed guide on how to troubleshoot and resolve the issue of a failed update or low battery that prevents the Ubuntu 22.04.5 LTS system from booting on a laptop.
Understanding the Issue
When a Ubuntu system fails to boot, it can display a white screen with the message "Oh no, something went wrong." This message can appear due to several reasons, including a failed update or a low battery. When the system fails to boot, it can also display the GRUB (Grand Unified Bootloader) menu. GRUB is the bootloader that enables users to choose the operating system to boot.
Failed Update
A failed update can occur due to several reasons, including a power outage or a sudden shutdown during the update process. A failed update can cause the system to become unbootable due to corrupted system files or dependencies that are essential for the system to function correctly.
Low Battery
A low battery can also prevent the Ubuntu system from booting. This is because the system requires a minimum battery level to perform a successful boot. If the battery level is too low, the system may not have enough power to complete the boot process, resulting in a blank screen or the "Oh no, something went wrong" message.
Resolving the Issue
Resolving the issue of a failed update or low battery on a Ubuntu 22.04.5 LTS system requires a few steps, including booting into recovery mode, checking for errors, and performing a system repair. The following steps explain how to resolve the issue:
Booting into Recovery Mode
To boot into recovery mode, follow these steps:
- Turn on the laptop and wait for the GRUB menu to appear.
- Highlight the Ubuntu (recovery mode) option using the arrow keys and press Enter.
- Wait for the system to load into recovery mode.
Checking for Errors
Once in recovery mode, it is essential to check for any errors that may have caused the system to become unbootable. To check for errors, follow these steps:
- Select the "Check all file systems" option from the recovery menu and press Enter.
- Wait for the system to check for errors and fix any issues found.
Performing a System Repair
After checking for errors, it is essential to perform a system repair to ensure that the system can boot correctly. To perform a system repair, follow these steps:
- Select the "Clean" option from the recovery menu and press Enter.
- Wait for the system to clean any unnecessary files or packages.
- Select the "Press Enter to continue" option and press Enter.
- Select the "dpkg" option from the recovery menu and press Enter.
