I had the choise to use version 12 or 13. I tried both. The results are the same.
I'm not sure what your problem is.
1. What version of Koha do you try to install?
25.11
2. However, I just found out I had a very similar problem years ago when I tried to install Koha 21.11 and 22.05 on Debian GNU/Linux 11. See the following thread:
https://lists.koha-community.org/pipermail/koha-devel/2022-August/047246.htm...
The solution that eventually worked for me is described here:

It seems that the hostname is part of the problem: /var/log/rabbitmq/rabbitmq-server.error.log has multiple: BOOT FAILED =========== ERROR: epmd error for host 34806: timeout (timed out) Kernel pid terminated (application_controller) ("{application_start_failure,rabbitmq_prelaunch,{{shutdown,{failed_to_start_child,prelaunch,{epmd_error,\"34806\",timeout}}},{rabbit_prelaunch_app,start,[normal,[]]}}}") Crash dump is being written to: erl_crash.dump...done my /etc/hosts: 127.0.0.1 localhost 127.0.1.1 34806.hostserv.eu 34806 # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters Thank you Beda
