Systemd service not working

[qshiroe]

My VPS provider has graphical.target enabled by default in Ubuntu 22.04

For this reason the services:

mailinabox.service
munin.service

will never start because of the presence of "After=multi-user.target"

Also because of this it is impossible to perform the installation because the process hangs at the stage "Installing Mail-in-a-Box system management daemon...".

In the conf/mailinabox.service and conf/munin.service files i replaced After=multi-user.target with After=network.target and the installation was successful.
