Gosh, I haven't worked with list servers in ages so I'm not sure if I'm doing this correctly.
I'm trying to help my installer team find an answer to this issue:
We have 2 Debian installers for Ubuntu. Let's say one requires Ubuntu 20.0.4 and the other is for a range of previous versions. Is there a way to force each installer notify the user that they are using the wrong version of our installer on the wrong OS? I saw a preinst script or a controller section but no clear way to specify the OS version that the installer is valid for.
Currently we get an 'unmet dependencies' message which doesn't describe the issue. We don't want the user to use -f to force the dependencies as installing older components is not generally a good idea.
