Going through your tutorial the first thing I noted was the command sudo apt update should be followed by sudo apt upgrade to update the system. but following that, I have encountered the following software installation problem When I enter the line:- git clone -b main [GitHub - pimoroni/pimoroni-pico: Libraries and examples to support Pimoroni Pico add-ons in C++ and MicroPython.](https://github.com/pimoroni/pimoroni-pico.git) --recursive I am asked for a user name and password? I entered name and password but git then says it needs an access token instead! However, the next step git clone -b main [GitHub - pimoroni/picosystem: PicoSystem libraries and examples.](https://github.com/pimoroni/picosystem.git) works! Any suggestions? ---

Hi Geoff Thanks for reading my tutorial :) I skipped the upgrade step for simplicity as it can take a while and I didn’t find it necessary for getting Pico dev up and going. I guess I’m making the assumption that folks are working with a newly set up Linux install like I was - did you need to upgrade yours before it would work? If Git asks you for a username and password it might be because you’ve got a typo in the URL - I can’t make out the exact command that you’re entering as the forum has added some unhelpful formatting to the URL. If you enclose the code in backticks (`) it should stop it from doing that, or you could post a screenshot/photo of the error? H ---

I’m thinking it was this command. `git clone -b main https://github.com/pimoroni/pimoroni-pico.git --recursive` ---

Just tried it and `git clone -b main https://github.com/pimoroni/pimoroni-pico.git --recursive ` seems to be working OK for me. It’s a public repo so no username/password should be required. ---

I didn’t try any of it, not into programing in C. As you mentioned making a typo will get you the password prompt, been there done that. It’s a head scratcher until you figure out your blunder. ---

Try `pimoroni-pico` instead of `pimoromi-pico` :) You can use Ctrl-C to copy the command from Windows and paste it into PuTTY by right clicking, if that’s easier than typing! ---
