I try to update my domain controllers. The Main DC is successfull updated. Now I try to update the BackupDC.
The Update breaks at 4.2-3 and no internet resources a available. If i ping local resources it works. But all resources outside my local network are not available
The Network-Settings i have controlled and they are correct. Can someone help me?
Hi,
no Internet available can have multiple reasons.
What does the following commands on your backup DC say:
ip a
ip route show
cat /etc/resolv.conf
ping 8.8.8.8
dig www.univention.de
ucr search --brief nameserver
ucr search --brief dns/forwarder
/CV
My Master DC ist 192.168.100.91 - Backup DC is 192.168.100.92 - The Router for Internet is 192.168.100.10
I hope you can read the results on the images 
Hi,
you do not have any default route set!
ip route add default via 192.168.100.10
And then you might need to check why it does not have the route. Double check network settings!

Thank you for the solution - now it works again. I can now update till 4.3-3 
OK - the solution is fine - but when i restart, then the route is gone. So I must execute the command again.
Can someone explain what is the reason? Can I put this informatin in ucs?
You can configure your default gateway through the web console (UMC) in the violet section.

Thank you for the reply. Here the Screenshot of the Network-Section. Thats the current settings. But if I restart the server, than the route missing again
If it is set correctly we should check why it is not getting through the system.
root@ucs:~ ucr get gateway
root@ucs:~ univention-check-templates
root@ucs:~ univention-s4connector-list-rejected
The latter one is assumed not to b relevant but just to make sure.

OK - here the results from a fresh rebooted system
Hi,
that looks really strange. Gateway is configured properly. I am unsure why the last command fails.
Could you try again to start the updater by:
univention-upgrade --ignoressh --ignoreterm
/CV
Should I add the default route before? When not, then I have no connection to internet
Hi,
well, how should the server contact the update host if is does not have an idea which gateway to use?
BTW: Could you try to post the output as text instead of screenshots? It is much easier to read as text instead of a picture…

Here the result:
`
root@ucs100092:~# univention-upgrade --ignoressh --ignoreterm
Starting univention-upgrade. Current UCS version is 4.3-3 errata390

Hi,
thanks. So it appears upgrade went well.
I currently do not know how the gateway variable is set to the system and why the route is not set.
And I realized you have removed your earlier screenshots. I would ask you to leave the posts as they are as this forum uses as reference for other users, too. They will not be able to verify if their issues matches the one here if the topic is crippled!
