Can you please how to install bc on Pynq Z2? I did try sudo apt update, I got the following message:
All packages are up to date.
W: Failed to fetch http://ports.ubuntu.com/ubuntu-ports/dists/bionic/InRelease Temporary failure resolving ‘ports.ubuntu.com’
W: Some index files failed to download. They have been ignored, or old ones used instead.
I then tried:
sudo apt install bc
