I set up a clean VM running up to date artful, which includes snapd-2.28.5+17.10 (so no copying of policy files or changing channel for core snap), and couldn't reproduce this. I started gnome-software, and tried to install the Hiri snap and got the expected polkit prompt.
I did get the following message though: Unable to install Hiri Failed to read from snapd: Error receiving data: Connection reset by peer Snapd restarted during the install, presumably after it installed the core snap, so this seems like another variation of bug 1718170. If you got a polkit prompt from the command line "snap" utility but not in gnome-software, that would indicate that it was not sending the X -Allow-Interaction header. We added that in snapd-glib 1.19, and you've got 1.23 installed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722195 Title: no policy kit auth dialog to install or remove a snap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1722195/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
