Previous question closed before I succeeded to find clarifying information. And thus I forced to re-post as a new question:

I'm looking for information regarding encrypted files that exist in Ubuntu Distribution media (20.04, 18.04, 16.04 maybe even earlier).

Our security procedures require a scan of any files that are transferred between network zones and unfortunately scan fails because of these files

Any idea, what are these files used for?

Here is the file: /pool/main/l/linux-firmware/linux-firmware_1.187_all.deb

The file located in the ubuntu-20/04-live-server-amd64.iso

    This file is not encrypted. You can open it with e.g Archive Manager. – Pilot6 Jun 18 '20 at 14:07

Normally nothing is encrypted - it might be that you mean binary-files.

You can search for any package in the repository via this page: https://packages.ubuntu.com/

Regarding the package linux-firmware_1.187_all.deb you can find a list of the included files here: https://packages.ubuntu.com/focal/all/linux-firmware/filelist

For further investigations I would recommend you to have a look at the source-code-package here: https://packages.ubuntu.com/source/focal/all/linux-firmware

and if you wnat to get fully into the rabbit hole take a look here: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux-firmware/tree/

Hope this was a help.
