Can't install GCC

[huahdgithub]

sources.list is the default:
deb [arch=riscv64] http://deb.debian.org/debian-ports unstable main deb [arch=riscv64] http://deb.debian.org/debian-ports unreleased main

When doing: sudo apt install gcc, I saw the message:

It works fine for me. Perhaps the error message (Temporary failure ...) is correct for a change, and this is indeed a temporary network failure.

OK. I realized I forgot to connect my board to the Internet. Now I need to figure out how to configure the IP, gateway, etc. Anyway, thank you very much!
