Ubuntu server 18.04 LTS does not use the proxy anymore












0















I have a Problem with one of my Servers. I am using one Proxy, but the Server does not accept the Proxy and tries to directly connect to the Internet. I checked where the Server wants to connect, thats how i know it is no Network issue. My Routing and Firewall works correct.



I tried to Google for the Problem but I did not find a solution. My guess is that I am missing one Setting where the Proxy should be entered.



This is what I did:





  1. Proxy in /etc/Environment for the whole system



    http_proxy="http://192.168.1.10:8080"
    ftp_proxy="ftp://192.168.1.10:8081"




  2. Added the Proxy in /etc/apt/apt.conf AND /etc/apt/apt.conf.d/proxy.conf since I Read thet the file changed with 18.04 LTS:



    Acquire::http::Proxy "http://192.168.1.10:8080";




  3. Tried to add the Proxy in the terminal:



    export http_proxy="http://192.168.1.10:8080"
    export ftp_proxy="http://192.168.1.10:8081"




Here is an example for one issue:



apt-key adv --keyserver keyserver.ubuntu.com --recv-keys *****


I get a timeout when I enter this command (with the correct key). My DNS works, I get the correct IP for all Servers and everything I want to connect to.



Can anyone help me? Thats all I found which I could try. When I had ubuntu Server 16.04 LTS, way 3 was enough to work, and way 1 was needed if I did not want to insert the Proxy in each session.
