Installing openntpd seems to break the installation

Hello once again. In relation to this topic

I guess that there is something wrong with the package management here. I had to install these packages:

atop htop iftop screen multitail iptraf bwm-ng console-data tmux wget locate openntpd

Long story short when i try to install openntpd this happens:

→ apt install openntpd

Use 'apt autoremove' to remove them.
The following packages will be REMOVED:
  cgroupfs-mount ntp python-univention-appcenter-docker univention-appcenter-docker univention-bind
  univention-docker univention-role-server-common univention-server-master

Do you want to continue? [Y/n]

It seems to me that something gets broken if i install that package.

Anybody can relate?

I think uninstalling:

  • univention-bind
  • univention-role-server-common
  • univention-server-master

breaks something. Can you confirm?

Thanks in advance

By default UCS already uses ntp, which is installed by default. This package conflicts with the OpenNTP package: The packages cannot be installed at the same time as both packages contain daemons, which bind to the same TCP/DUP ports. Installing OpenNTP thus would remove ntp from you system. As this package is a hard dependency of other packages, they would be removed as well. This would render your UCS system incomplete and mostly unusable.

I understand, thank you very much. I will mark this as solved and i guess i have found an explanation to this problem and to my other post.
