I am sorry Peter. Thank you for trying to help, but I am a medical man, not an IT guy. I don't know what you mean. I am assuming you are an IT guy. Imagine I am your doctor telling you what is wrong with you, but you understand very little because I am abbreviating greatly and using medico-speak. That is where we are. Now, I have interpreted your suggestion (probably wrongly) to mean I should use "show variables like 'datadir';" as a command in the terminal. Well, I did that and this happened. Reply in baby language please. Thank you!

The program 'show' can be found in the following packages:
* mailutils-mh
* nmh
Try: sudo apt install <selected package>
