Sallymelek that’s very odd. I don’t understand why it refers to
-usnano if that isn’t what was entered. In (in the SSH console window) press the up arrow key repeatedly, this cycles through a history of commands entered.
Can you check using this method to ensure that “nano” wasn’t inadvertently added to the end of the command ? It just strikes me as somewhat odd that of all the words to be entered, it’s nano, and you’re using that as an editor 🤔
