[ubuntu-hardened] What are the dangers of installing packages on open Wi-Fi?

[Jason Franklin]

Greetings:

My company uses both Debian and Ubuntu for employee workstations.

Since we travel with these workstations, we often find ourselves on an
open Wi-Fi connection when we need to install packages (hotels, coffee
shops, etc.).

What are the risks of installing packages from the official Debian or
Ubuntu repositories when connected to an open/public Wi-Fi access point?

Thanks,
Jason Franklin
