My new laptop's network card doesn't work and I need aircrack-ng for a dongle, which means I need dkms. It's there in the package pool in the installation iso, but the installer tells me to reboot after install and then I can't figure out how to easily install anything from the pool, which seems like an obvious thing to want to do in this case. I can dpkg --install the individual .deb files and take care of dependencies one at a time but bleeeech.

How do I arrange to look in the installation medium I just used for additional packages?

I don't mean to be mean but honestly as things are I'm not sure I'd have the installer even pretend to work if the network isn't there. Everything seems to be set up assuming it.

From the bottom of the launchpad, click on the dots, select Software & Updates, and at the bottom of the screen, there is a checkoff to select the DVD for searching for packages.

I see the active button on a full 22.04 install, and on a 23.10 ISO booted from disk. The full install has the commented line: # deb cdrom:[Ubuntu 22.04 LTS Jammy Jellyfish - Release amd64 (20220419)]/ jammy main restricted

I don't see an active button (like you see) on full 23.04 and 23.10 installs and a 23.10 vm.

The program apt-cdrom allows you to add sources for packages. See the man page. The list of such added sources is kept in file /var/lib/apt/cdroms.list.

cat cdroms.list
CD::a50676044fa2ce120515c2a6c57bb3c7-2 "Ubuntu 22.04 LTS _Jammy Jellyfish_ - Release amd64 (20220419)";
