Two days ago (Saturday) I updated my installation of mail-in-a-box. I make a new virtual machine in a ubuntu 18.04 and i move the backup to this new machine. It was working well on saturday and sunday.
Today (Monday) the server works fine during morning, but at 11:00 we notice that the mails didn’t arrive.
I am checking the installation but it seems that all is fine, so i run again the installation command
curl -s https://mailinabox.email/setup.sh | sudo bash
And I notice the following error after the screen to write the hostname:
RTNETLINK answers: Network is unreachable
I suppose that it can be the key to solve the error. ¿anybody can help me?
