This is the first question you get to solve in picoctf.
Unless you solve this problem you cannot proceed any further 😦 but it is a very simple one.
The ‘:20’ indicates the marks you get when you solve the sum for your team. Here is the question.
After opening the robot’s front panel and looking inside, you discover a small red button behind a tangle of wires. Pressing the button lights up the robot’s primary screen. It glows black and quickly flashes blue. A line of small text types out:
The text refreshes and displays the prompt:
FILE SYSTEM RECOVERY INITIATED... FILE SYSTEM COULD NOT BE IDENTIFIED... PLEASE ENTER FILE SYSTEM FORMAT:
And you will have a submit button below it ( to submit the ans ).
You need not know about all the type of file system to submit the answer. But still if you feel to know about them here are some useful links
And as the clue specifies this can be solved by doing a simple web search of the error which will lead you towards the right answer.
Here is the screenshot of the question
After this you get a four more questions to solve. Carry on 🙂
