The Ubuntu Desktop team has created the gnome-3-38-2004 snap which provides supported libraries needed for GNOME 3.38 apps on 20.04 via a content interface. This snap is the supported means for building GNOME 3.38 snaps on a core20 base, just like gnome-3-34-1804 was for 3.34. We would like a snap declaration to auto-connect this interface.
I would also like to request transfer of this snap to Canonical.
Thanks for your consideration
