Hi Thomas,
Thanks for your reply.
I tried to put this in sources.list:
deb file:/media/deploy/UUI buster main
--Where /media/deploy/UUI is the mount for the USB stick
Running apt-get update, I get this:
root@deploy-pc:~# apt-get update
Get:1 file:/media/deploy/UUI buster InRelease
Ign:2 cdrom://[Official Debian GNU/Linux Live 10.2.0 gnome 2019-11-16T10:36] buster InRelease
Ign:1 file:/media/deploy/UUI buster InRelease
Err:3 cdrom://[Official Debian GNU/Linux Live 10.2.0 gnome 2019-11-16T10:36] buster Release
Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs
