Problems with the first notebook: Downloading Dependencies and Configuring your Environment

[AlexZome]

Hi,
I have been trying to download riscv-gnu-toolchain into the pynq-z1 board, but it seems that several errors happens when I execute the following code: !git clone --recursive https://github.com/riscv/riscv-gnu-toolchain /home/xilinx/riscv-gnu-toolchain and the output window looks like this:

I have tried to download the dependencies a couple times, but I get the same errors. Also I have checked the folders of the toolchain and are empty.

Do you know how can I fix that?

Thanks in advance.
