Answer 1

Looks like it's trying to use IPv6. I bet your connection doesn't have IPv6 (yet).

Make a config file that disables IPv6.

Run the command sudoedit /etc/apt/apt.conf.d/99force-ipv4, put Acquire::ForceIPv4 "true"; in it then save it.

If you want a temporary solution, run apt-get -o Acquire::ForceIPv4=true update instead of just apt-get update to make it use IPv4.

Answer 2

Seems like you don't have internet connection. Make sure you are connected and try again.
