Opera starts building snap packages with gnome-3-28 extension and core18 base. We would like to have auto-connect to gnome-3-28-1804 interface for the desktop environment it needs.
You can test the opera-developer build on its edge channel:
snap install opera-developer --edge
Please noted that opera, opera-beta and opera-developer will need to auto-connect to gnome-3-28-1804. New snaps for opera and opera-beta will be uploaded later.
Thank you very much!
