"Installer defaults" is a very broad term, and the contents of your
installation can differ dramatically depending on the type of install
media used.
Besides it's really been awhile since I used Debian Installer CD1. I
prefer d-i over TFTP these days. More flexibility, less cruft this way.

And that means you're using NetworkManager, wicd, systemd-networkd,
connman or whatever they put in there by default. Not the conventional
ifupdown.

To my best knowledge this particular invocation of dpkg does not involve
network communication in any way. Therefore it's a different problem.

And that, ladies and gentlemen, shows us two things.
First one being - you IPv4 settings are working.
Second - those corporate drones at Opera are unable to setup a proper
Debian repository.

That's expected. Apt discarded faulty Opera repository and found 26
proper Debian packages to update.


> Any further help in resolving this problem, will reallly be appreciated!

I count three problems:

1) "dpkg --add-architecture i386" does not work. 

2) Your IPv6 setup is broken.

3) You want to use Opera repository, but are unable to do so.

Which one will be the first?
