Hi Wizard. Your summary is correct. As I was thinking about this problem. I do remember a pop window that informed me that something (not sure what it was) was not able to load when I installed the OS. Your summary is correct. I can unlock the OS but not the "sudo" and I have not been able to enable the firewall. Prior to executing the command. I decided to input my password at the prompt to be able to see my password so that I can be sure that there was no error in the keyboard. The password displayed correctly. My hunch is that something happened during the install. Perhaps a corrupted file. I just booted the OS and there is definitely some issue with the keyboard. I am attaching a picture of the keyboard. AS you can see the "@" and quote symbols are not in the usual places. Let see if I can get those files you requested. Ok, I found the keyboard file and here it is. you guys are awesome, In my spare time I am building a wood gasifier to provide fuel for a genset to power your house in times of power outages. I digress that is for a different forum.
