Sure! Here's an updated README.md for your auto_select_mirror_ubuntu repository, including the new steps for single-command installation and execution:

auto_select_mirror_ubuntu is a script that automatically selects and sets the appropriate Ubuntu repository mirror based on your system's version. The script fetches the list of available Ubuntu distributions from a mirror, checks your system's codename, and sets the repository URL accordingly.

• Automatically detects your Ubuntu version's codename.
• Fetches available distributions from a mirror.
• Sets the correct repository URL for your Ubuntu version.
• Backs up your current /etc/apt/sources.list before making changes.
• Updates the package list for the new repository.

• Ubuntu-based system.
• wget must be installed (usually pre-installed on Ubuntu).
• sudo privileges for modifying system files.

To download and run the script in a single command, run the following:

curl -sSL https://raw.githubusercontent.com/Sajibekanti/auto_select_mirror_ubuntu/main/auto_select_mirror.sh | sudo bash

This will:

1. Download the script from GitHub.
2. Make it executable.
3. Run the script with sudo privileges.
4. Automatically clean up the downloaded script after execution.

If you prefer to download and install the script manually, follow these steps:

1. Clone the Repository:

   git clone https://github.com/Sajibekanti/auto_select_mirror_ubuntu.git
   cd auto_select_mirror_ubuntu

2. Make the script executable:

   chmod +x auto_select_mirror.sh

3. Run the script:

   sudo ./auto_select_mirror.sh

1. Get Current Ubuntu Codename: The script uses lsb_release -c to get the codename of your current Ubuntu installation (e.g., jammy, noble, etc.).

2. Fetch Available Distributions: The script fetches the list of available distributions from https://mirror.limda.net/ubuntu-archive/dists/ using wget and checks if your codename is listed.

3. Update Sources: If the codename is found, the script updates your /etc/apt/sources.list file with the correct repository URL for your Ubuntu version.

4. Backup: The script backs up your original /etc/apt/sources.list file to /etc/apt/sources.list.backup before making any changes.

5. Update Package List: Finally, it runs sudo apt update to refresh the package list from the newly set repositories.

• Distribution Not Found: If the script cannot find your codename in the list of available distributions, it will exit with an error:

  Error: Distribution 'noble' not found in the available mirror list.

  In this case, please ensure that your Ubuntu version is supported or check if you're using a pre-release version.

You can modify the following variables in the script:

• MIRROR_URL: The base URL of the mirror from which the available distributions will be fetched.
• REPO_URL: The base URL for the repository (set to http://mirror.limda.net/ubuntu-archive/ by default).
