I have the same problem since 17.10, running currently 18.04. Reinstalling gnome-software did not help.
gnome-software does not show apt updates at all. I have to update system using apt from terminal or update-manager Found similar issue in debian mailinglist, but related only to empty updates list: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851796 Adding attachment file with gnome-software running with --verbose command, 9581 is the line where I've typed in other terminal: "sudo apt update". ** Bug watch added: Debian Bug tracker #851796 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851796 ** Attachment added: "verbose_gnome-software" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1734095/+attachment/5176480/+files/verbose_gnome-software -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734095 Title: After upgrade to ubuntu 17.10 Software & Updates not showing authorization popup [gnome-shell[N]: pushModal: invocation of begin_modal failed] To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1734095/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
