Linux CLI guided exercise

I am doing the Linux CLI Basics lab and when I get to Part 2: file operations and try to do the first command “mkdir labwork” my system says it cannot create new directory “labwork” because the file exists. please help, I tried starting over 4 times already

When you log out of the lab environment, and then log back in, you will end up on the same desktop you were last on, with any changes you made (like if you created the labwork folder).

To get a clean environment, click on the Machines tab and click Restart Lab:

That being said, if the labwork directory exists, you can just use it (cd labwork).
