I am encountering issues with my Ubuntu 20.04 server running on Oracle, as I have forgotten the root password. Unfortunately, I am unable to access the GRUB menu to initiate password recovery. Could you please provide guidance on how to reset the root password under these circumstances?
Additionally, I mistakenly closed the firewall, which is now preventing me from accessing the aapanel panel. Is there a way to modify the firewall settings without requiring root privileges?
Your assistance in resolving these issues would be greatly appreciated.
Thank you.
