How to Resolve ACPI Errors When Installing Ubuntu 22.04 on ASUS GA502GU-PB73

-

Introduction:

While attempting to install Ubuntu 22.04 on ASUS GA502GU-PB73, the installation process halts with ACPI BIOS errors, specifically "ACPI BIOS Error (bug): Could not resolve symbol". This indicates a potential incompatibility with certain hardware components or incorrect BIOS/UEFI settings.

ASUS does not officially support Linux distributions like Ubuntu, so the exact cause of issues cannot be clearly identified.

However, it's possible that some hardware components in this laptop may not be fully compatible with certain Linux distributions or kernel versions. Additionally, problems related to ACPI (Advanced Configuration and Power Interface) can occur if the BIOS or UEFI settings are not configured correctly.

Step 1: Temporary Fix in GRUB

To proceed with the installation, you need to modify the boot parameters:

  1. Boot from the Ubuntu installation USB.
  2. At the GNU GRUB menu, select "Try or Install Ubuntu".
  3. Press 'e' to enter the GRUB bootloader edit mode.
  4. Add acpi=off at the end of the command line.
  5. Proceed with the installation.



However, towards the final stages of installation, there can be a failure in configuring GRUB. When this happens, only the GRUB prompt appears upon restarting



Step 2: Dealing with GRUB Post-Installation

Post-installation, the system might fail to configure GRUB correctly and only the GRUB prompt appears upon restart.

To fix this:
  • Boot from the Ubuntu installation USB again.
  • Install and run Boot Repair with the following commands:
# sudo apt-add-repository ppa:yannubuntu/boot-repair
# sudo apt-get update
# sudo apt-get install -y boot-repair


Step 3: Repair Grub using "Boot Repair"

  • Run Boot Repair through Launcher or terminal

# boot-repair

  • In Boot Repair, select 'Recommended Repair', and Restart your system.

If you're a frequent user of SecureCRT , backing up your session settings and restoring them later is crucial—especially when migrating to a new PC or recovering from a crash. In this guide, you’ll learn how to manually back up and restore SecureCRT settings on Windows , ensuring you never lose your configurations again. Does SecureCRT Have a Built-in Export/Import Feature? Yes, SecureCRT provides built-in export and import features in the Tools menu. However, these features may not capture all configuration details such as: Backup scripts Custom login scripts Certain session-specific files Therefore, if you want to completely clone your SecureCRT environment—including every session and customization—the safest option is to manually back up the entire Config folder. What Is the SecureCRT Config Folder?

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-
Image
Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running. My Setup NAS Model : Synology DS916+ DSM Version : DSM 7.1-42661 Update 1 Docker Image : vaultwarden/server Ins...
