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?
