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
