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 Desktop Packages, 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 Status in gnome-control-center package in Ubuntu: Confirmed Status in update-manager package in Ubuntu: Confirmed Bug description: The Network Proxy settings available under Settings/Network are not applied system wide. Unlike 16.x, there is no "apply system wide" setting. Setting a proxy here: - does not modify /etc/environment - does not set root's http_proxy, https_proxy, ftp_proxy environment variables This means that apt and Software Updates do not receive the proxy settings, and package checks/updates/installs fail. workaround: sudo http_proxy='http://[username]:[password]@[webproxy]:[port]' apt update etc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1730672/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
