1. Question1--E: Failed to fetch http://mirrors.163.com/ubuntu/dists/jammy/main/binary-armhf/Packages 404 Not Found [IP: 60.191.80.15 80]?

Answer: the system of PYNQ-Z2 img 3.0 is Ubuntu 22.04 jammy, so we should replace apt source /etc/apt/source.list.d/multistrap-jammy.list

2.Question2--E: /bin/sh: 1: /home/xilinx/riscv-gnu-toolchain/binutils/configure: not found

Answer: This is because we try to move riscv-gnu-toolchain(downloaded by windows) to the linux system of pynq. Maybe it may be caused by insufficient execution permissions for some configure files. And we have not found the solution.

So the good method is downloading the riscv-gnu-toolchain on pynq board or linux.
