You got it in one. I am using the network installer to create an offline installer (for secure non-connected to internet computers). However, When I am installing from the offline cache, the install is failing and I can’t figure out why. The documentation for the OSGeo installer is very sparse.
I will look closely at the link you posted, thank you very much. But it seems at first glance to explain how to create a custom package, not install existing ones. Were you thinking I should create my own meta-package using this method?
