Maybe a bit more information about how your network is setup. I have installed it both in ubuntu 16.04 and 18.04 LTS and it worked. Could you have a connectivity issue?
Also install tcpdump and use the -w option to write a pcap file, then open in wireshark might also help.
If you post some more information, people here may be able to help.
Hi Jake,
thanks for you reply. The network setup is pretty easy, only one firewall between my server and the internet access. I just add a rule that every traffic from my server to the internet is allowed, just to be sure that nothing is blocked. There is no proxy or something else.
Then I started a packet-capture on my firewall, for the first test this was the easiest way for sniffing, and i got the same error as before. Then i noticed a typo in my ip-address filter. But theb some magic happend and my second try works completely normal. I got the .deb package. Please don’t ask why!
I try it a few times more: 2 times freeze, 1 working access, than again freeze and last time was ok. Something is strange but i habe no idea why this is happening.
I would like to say, that everything is fine now but i got the next problem:
i did dpkg -i graylog-2.5-repository_latest.deb for installing the package but with apt-get install graylog-server (with apt-get update first) i only get: Package not found
