Description Emelie cendio

When running tl-setup on Ubuntu 24.10, it fails to install the postfix dependency. 

To try to resolve the issue, an attempt to install postfix manually was made, where we can see that the installer asks for more input in a gui, before the installation can complete.

It looks like tl-setup can't continue installing, since we have no way of handling such situations.

After tl-setup fails, it is also not possible to install other packages, e.g. directly with apt.

It can be fixed by removing '/etc/postfix/main.cf' followed by running 'systemctl reload postfix', but users should not have to do these steps to be able to complete the setup...

In tl-setup text:
Similar message as in the GUI

Debian/Ubuntu have worked to make sure packages don't require any interactive input, so that they work well with GUI frontends. So this bug is a bit surprising.

Let's wait a bit and see if this is a bug that Ubuntu will resolve before digging further.

This error was due to our Ubuntu 24.10 VM having the hostname 'ubuntu-24.10'. The '.' in the hostname is invalid and breaks postfix. Simply removing the '.' from the hostname (or from the parameter mydomain in /etc/postfix/main.cf).
