Hi Till, Just wanted to ask if you are aware of any issues regarding Ubuntu Server 18.04.x / ISPConfig 3.1 and mirror config?? Before reconfiguring it all I will be doing a installation similar to this: The Perfect Server - Ubuntu 18.04 (Bionic Beaver) with Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot and ISPConfig 3.1 KR Dan
Yes, that should work in the same way as you set it up with Debian. Just use the perfect server guide Ubuntu 18.04 for the commandas and the Debian Multiserver guide as guidance on how to join the servers.
