Are you using ipv6? If so, you might need to force apt to use ipv4, e.g. sudo apt-get -o Acquire::ForceIPv4=true update. The -o Acquire::ForceIPv4=true config will force ipv4.

I think I used https://www.ostechnix.com/how-to-force-apt-package-manager-to-use-ipv4-in-ubuntu-16-04/ as inspiration.

To get the most objective possible trace of network traffic Wireshark can be used.

Wireshark is a network protocol analyzer that makes it extremely simple to capture and trace network activity from any source on your computer. It also has
