Network problems after reinstallation

UCS - Univention Corporate Server
1

Hello, everybody,

I am currently installing a new UCS 4.4. the installation runs without errors but the package management does not work after that.

The network works:

root@srv01:~# ping updates.software-univention.de
PING updates.software-univention.de (176.9.114.147) 56(84) bytes of data.
64 bytes from download2.software-univention.de (176.9.114.147): icmp_seq=1 ttl=54 time=9.30 ms
64 bytes from download2.software-univention.de (176.9.114.147): icmp_seq=2 ttl=54 time=9.44 ms
64 bytes from download2.software-univention.de (176.9.114.147): icmp_seq=3 ttl=54 time=9.33 ms

root@srv01:~# cat /etc/resolv.conf
domain	gehr.local
nameserver  192.168.24.5
options timeout:2

The server is the master with the IP = 192.168.24.5, the gateway has the IP 192.168.24.254.

The files 15_ucs-online-version.list and 20_ucs-online-component.list are empty

The debug script gives me:

root@srv01:~# python sources-list-debug.py 2>&1 |tee sources-list-debug.log
Traceback (most recent call last):
  File "sources-list-debug.py", line 7, in <module>

    raise ConfigurationError(uri, reason)
univention.updater.errors.ConfigurationError: Configuration error: Network is unreachable

I have already repeated the installation twice. The problem occurred each time.

This is the issue!
If they are empty, how should UCS determine which servers to use for update?
Do: ucr commit /etc/apt/sources.list.d/ and check if they are still empty. If so, verify you ucr variables: ucr dump| grep repository

Yes, I know

yes, after that is still empty

root@srv01:~# ucr dump| grep repository

this is my first installation on a Proxmox VM host. I did the UCS installation as usual and repeated it several times. Always the same problem. I also tested it with UCS 4.3. Same problem.

During the new installation (manual IP) of the master, I always make the following

DNS entries: [IP from Master him self] [IP Default GW]

Example:

Master should get the IP 192.168.24.5. The default gateway is 192.168.24.254, which I specify when installing the master:

DNS: 192.168.24.5 192.168.24.254

Could this be the problem?

The problem was not with UCS. I suspected Proxmox but in the end it was the PFSense running as VM on Proxmox
