Cuda installation failed

Hi Team,

I’m trying to uninstall nvidia driver using command “/usr/bin/nvidia-uninstall” but it is not getting uninstall.
I’m getting this error message whenever I’m trying to uninstall it -
ERROR: Failed to run /usr/bin/nvidia-xconfig --restore-original-backup:

ERROR: Unable to restore from original backup file
‘/etc/X11/xorg.conf.nvidia-xconfig-original’ (No such file or

Using X configuration file: “/etc/X11/xorg.conf”.

This is not happening on my personal PC. this is happening on cluster nodes.
Will it be safe to perform the DDU on cluster nodes?
Could you please help me here?
