I can confirm that bug for a fresh installed 18.04 working behind a corporal http/https-proxy that requires authentication.
Although configuring Settings/Network, environment config file, apt and all gsettings under org.gnome.system.proxy including authentication correctly, Ubuntu-Software-GUI displays the following error message when trying to update: “… failed to download https://extensions.gnome.org//static/extensions.json: Proxy Authentication Required” and “… failed to download https://cdn.fwupd.org/downloads/firmware.xml.gz.asc: Proxy Authentication Required” Yes, I can work around it by using apt on command line. But: Apparently Ubuntu-Software, the key tool for maintaining system security, does not work behind an authenticated proxy. Should that not be reason enough to value the bug higher than low? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
