Hi Vasilis,
Please note that this is not a good support channel, but a contact point
to reach the developers directly. Many – this question included – can be
far better and detailed explained by contributors providing support
through dedicated channels.
I think you can find more information about the available options at:
https://www.ubuntu.com/support/community-support
Case in point: I don't have an Ubuntu system, so I can't explain how to
do it there, I can at best give general hints as follows if you want to
continue on your own, but I would really advice you to get in touch with
your supporters!

If the file does not exist (which is okay and probably the default) you
can create it with a text editor (= not with an office suite tool).
Better yet you can create a file in /etc/apt/apt.conf.d/ with a name of
your choosing. The syntax of the file(s) is explained by "man apt.conf".

I have no idea what you mean here as I have no knowledge of the more
user-facing parts of the picture, but assuming these tools set the
environment variable http_proxy – which apt reacts to as many other
commandline tools do – I would check if it is set in your case, so in
your shell try: export | grep -i proxy
A clean restart (or at least restarting your Terminal application) might
very well cause the settings to propagate to the right places.

Details about apt specific proxy configuration as well as about what apt
understands from more generic configuration options is detailed in "man
apt-transport-http" (assuming your distributions includes a relatively
recent apt version as the manpage is relatively new. In that case you
can also read it online through; the options detailed exist for a long
time, they were just documented in different places before).
If the support channels can't help you or if you run into a bug feel
free to get back to us (in the later case, the supporters will even help
you create a good actionable bugreport if you need help with that).
Best regards
