CUBIC custom 20.04 ISO fails testing phase

cc flag

I need to customize an install of Ubuntu 20.04 Server to include a few packages since my bare metal server is 'offline'. I downloaded 20.04.5 live ISO, went through the default CUBIC steps and it fails 'test'. I then downloaded 20.04.1 legacy server, walked through the steps of CUBIC and it too fails testing. The error I receive is

"Your installation CD-ROM couldn't be mounted. This probably means that the CD-ROM was not in the drive. If so you can insert it and try again. Retry mounting the CD-ROM?"

I really need to complete this task as soon as possible, I've already spent hours troubleshooting.

Thank you for your time and expertise, Steve

Why not use the 20.04.6 ISO? (*officially not released; so it's still a RC (*release candidate*), but it's late and the only issue with it was a nvidia module that I suspect you won't miss*). I have no experience with Cubic, but an alternative is an untouched *live* system written using persistence etc (so you have an additional area on thumb-drive) & you run a script to install the packages from the persistence area post-install...

in the CHROOT step of the process with cubic I run the upgrade cmd and it upgrades to the 20.04.6 version of Ubuntu server. the difference is the installer is the legacy installer system

FYI: 20.04.6 has been released; https://lists.ubuntu.com/archives/ubuntu-announce/2023-March/000287.html so you're using an *outdated* ISO now officially.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
