Installation Fails Ubuntu 20.04/22.04 – PowerDNS or Pure-FTPd Startup Error

Hello,

I’m encountering an installation failure when setting up CyberPanel on Ubuntu 22.04. The installer fails while trying to start pdns (PowerDNS):

[07.25.2025_10-50-00] #########################################################################
[07.25.2025_10-50-00] Running systemctl start pdns failed. Running again, try number 3

journalctl -xeu pdns.service

Jul 25 10:50:47 vps systemd[1]: Starting PowerDNS Authoritative Server...
Jul 25 10:50:47 vps pdns_server[18851]: Unable to launch, no backends configured for querying

Jul 25 10:50:47 vps systemd[1]: Failed to start PowerDNS Authoritative Server.

If I try installing without PowerDNS, the same type of failure happens for Pure-FTPd.

  • This issue only occurs on Ubuntu 22.04 and 24.04.
  • On AlmaLinux 8/9, installation completes successfully.
  • Tested on clean minimal Ubuntu 22.04 installations with the official CyberPanel installer.

Has anyone encountered similar issues? Are there known compatibility problems with Ubuntu 22.04?
