Usage Notes

The script must be executed as the root user.

Install lrzsz to transfer the script (e.g., sudo apt -y install lrzsz on Ubuntu).

Run the script with bash reset_v10.sh (or the appropriate version file).

After launch a menu is displayed with 26 numbered options covering all supported tasks.

Select the desired option number and follow any prompts (e.g., entering a new root password, choosing a repository, etc.).

For CentOS Stream 9/10, ensure the auxiliary update_mirror.pl script is present in the same directory before selecting repository options.

After completing configuration, reboot or log out/in to apply changes.

Example Commands (Ubuntu)

# Install transfer tool
sudo apt -y install lrzsz
# Receive script
rz -E
# List files
ls
# Execute script
bash reset_v10.sh

Example Commands (CentOS Stream)

# Install transfer tool
dnf install -y lrzsz
# Receive script
rz -E
# List files
ls
# Execute script
bash reset_v10.sh

After the script finishes, you can use the menu to perform additional tasks such as disabling firewalls, configuring SSH, or installing recommended packages.
