Help!!! I am trying to finish a project for uni but unfortunaly, my Raspberry Pi 3 is not even able to detect my GrovePi? Any advice on what to do? I will be thankful forever! I attached the trouble-shoot output.

Checking for firmware version

There are a few things I can recommend right away:
-
Are you using Raspbian Bullseye? That will NOT work with the Grove-Pi board. You should download the “legacy” version, (Buster) and use that.
-
Did you go to
sudo raspi-configand make sure that i2c and SPI are enabled? You might want to turn on SSH at the same time. -
Did you install the Grove drivers? There is a thread here that discusses just that problem.
-
Are you using a virtual environment? Don’t. It won’t work.
Give those a try and let us know what happens.
@jimrh Thanks for your reply! 
- I use the “legacy version”
- Yes, I enabled them!
- I am not sure what that means but I will check!
- No, I don’t
Still get the same error (Could not open “/dev/i2c-0” No such file or directory)

What concerns me is that when you’re checking i2c buss 1, (sudo i2cdetect -y 1), you’re getting nothing. There should be devices enumerated there.
My own robot, (not a Grove board), returns data like this:
pi@GoPiGoOSTest:~ $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- 06 -- 08 -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- 29 -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
pi@GoPiGoOSTest:~ $
Each of the numbers represents an enumerated device and the “UU” at address 68 represents the Adafruit real-time clock bound to the kernel via a device tree overlay.
As you can see, there should be something there if the board is active and i2c is enabled and active.
Do a forum search for “Grove” and look for later posts.
have you removed and re-mated the Grove from/to the RPi checking for any bent pins?

That is not an error - or perhaps call it an expected error for Bus 0 which is no longer used. Ignore it.
Issue is you are not seeing I2C Bus 1 devices. This is likely i2c not enabled, or mechanical pin issue, a failed (read-only) SDcard, or bad board.
