First boot into command line.

columboscoat

@julian2000P Just type each command and enter. When the script runs you will get a grey box on a blue background. Choose basic install.

julian2000P

I typed in these three commands:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git lsb-release

should I also type in these?:

git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git
sudo ./retropie_setup.sh

columboscoat

@julian2000P yes. They are 2 separate commands.

columboscoat

Just do and type exactly what the guide says.

julian2000P

I typed in all five commands but nothing happened.

columboscoat

@julian2000P Nothing at all. No errors or command not found or bash errors. Literally nothing?

julian2000P

after typing in 'sudo apt-get update' some errors occurred

rbaker

@julian2000P Have you downloaded the correct image? i.e. Not the first one for Pi 0 and 1?

columboscoat

I'm sorry. You need to be more specific if you want help. I can't drag the information from you. Anyway, good luck. Perhaps someone else with more time and patience will offer assistance.

julian2000P

I downloaded it for pi 2/3

@julian2000P said in First boot into command line.:

What errors?

julian2000P

@columboscoat thank you anyway

julian2000P

at the end it says
some index files failed to download. they have been ignored, or old ones used instead

rbaker

@julian2000P What is your power supply?

julian2000P

I don't know the brand, but it has a 5 V output and 750mA

rbaker

@julian2000P Then that is your problem. A Pi3 requires 5V@2.5A, you need to check the instructions for the Pi before installing stuff. You might just get away with it on a Pi1 but with stuff connected on a 3, no.

Did you read this:

Point 4 states: If using a Raspberry Pi - make sure you have a sufficient Power Supply / power cable. Many issues are related to having a poor PSU

julian2000P

I hope that will fix the problem , thank you

rbaker

@julian2000P Check here https://www.raspberrypi.org/help/faqs/#powerReqs. If it still does not boot, you could have a corrupt card or a faulty card. Try another.

julian2000P

I finally got a new power supply, but i have still the same problem. I use a sd-card with 8 gb, is that enough?

rbaker

@julian2000P how many raspberries do you see during boot?
