/etc/apt/sources.list

[tommy1024]

Hello, here is installed Kali 2.3 - but it is somehow closed off from update-server.

In sources.list is written :

deb http://http.kali.org/kali kali-rolling main non-free contrib

But this is somehow not accepted and apt-get update is ending with "temporary failure", it seems
that name of kali-server is written wrong at kali.org and is then not connecting with Kali 2.3

What should I do ? Is concerning server at moment down ? Should I wait, or should I re-type sources.list
for Kali 2.3 ?

Looks like the correct entry, but you can always verify at http://docs.kali.org/general-use/kali-linux-sources-list-repositories

The repos might have been down then. I'm able to do apt-get update && apt-get dist-upgrade ok from my location.

maybe try "deb http://http.kali.org/kali kali-rolling main contrib non-free"?

you wrote "non-free" and then "contrib". maybe that's the issue.
