Thorsten - you can workaround a few different ways. For me, it's a pain because I move from a proxy-only to a non-proxy environment as I move my workstation around.
Workarounds: 1. set the http_proxy, https_proxy, ftp_proxy environment variables in root's environment, reboot. 2. prefix any apt command with the variables,ie sudo http_proxy='http://[username]:[password]@[webproxy]:[port]' apt update sudo http_proxy='http://[username]:[password]@[webproxy]:[port]' apt upgrade sudo http_proxy='http://[username]:[password]@[webproxy]:[port]' apt install [package] Hope that helps. Proxy issues have been appearing on and off in Ubuntu for a long time (9.x). They usually get sorted out eventually. etc -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730672 Title: Proxy settings not applied system-wide, are not used by Software Update or apt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1730672/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
