I'm installing packages into my custom ubuntu server ISO for a complete offline install via this guide: How to create a Customized Ubuntu Server ISO?. The only option for the install is a single dvd. No way to plug in a usb or connect to the internet to install packages. Must be able to put the dvd in, install and that's it - good to go.
Everything works great except when the initial install tries to install these extra packages... it breaks on unmet dependencies for the dependencies of these packages.
Example:
extra package I'm installing during initial system install -> its dependencies -> dependencies for those dependencies - BREAKS HERE -
This wouldn't be an issue if I knew which ones I needed to download ahead of time to put onto the iso! However, I cannot tell which ones will be needed until I load the dvd up and try to actually do the install and watch if it breaks.
There must be an easier way to do this... right? I'm already downloading all first level dependencies needed just in case. Should I extend that out one more level?
